rust-bitcoin

This commit adds documentation showing the project's internal crate dependency tree and a helper command to regenerate it. It does not change any executable code, cryptographic logic, or network handling, so it has no security impact on its own.

This commit is a routine code cleanup that changes how internal Rust import statements are written. It replaces direct imports from internal sub-crates (like `units::BlockTime` or `primitives::Sequence`) with imports through the crate's own public re-exports (like `crate::BlockTime` or `crate::Sequence`). There is no change to program logic, behavior, or security.

This commit changes one word in the README.md file, replacing 'MR' (merge request) with 'PR' (pull request). It is a documentation-only terminology fix with no code changes and no security relevance.

This commit fixes a typo in an error message. The message previously said 'lock-by-height' when it should have said 'lock-by-time'. It does not change any program logic, calculations, or security behavior.

This commit fixes two spelling mistakes in code comments: adding a missing space in a comment about Rust formatting and changing 'a authentication tag' to 'an authentication tag'. No program logic, cryptographic code, or behavior was changed.

This commit simply updates a single text file that records which nightly version of the Rust compiler the project's automated tests use. It changes one date to another newer date. There is no code change, no bug fix, and no security relevance visible in the commit itself.

This is a one-word documentation fix in a code comment. The developer corrected the name of an iterator type in a rustdoc comment so it matches the actual returned type. No code behavior changed, and there is no security issue.

This commit is a cosmetic code cleanup in the rust-bitcoin library. It replaces fully written-out module paths (like `crate::Txid`) with shorter imported names (like `Txid`) in the PSBT error definitions. The commit message and diff show no functional changes—only style improvements.

This commit fixes a single spelling mistake in a code comment, changing 'inefficientcies' to 'inefficiencies'. No program code, logic, or behavior was changed. It has no security relevance.

This commit simply adds a second developer's name to the author list in a package metadata file. It changes no code, no functionality, and has no security relevance.

This commit only fixes grammar in comments and a shell script help message. No code behavior is changed, so it has no security relevance.

This commit fixes a bug in the rust-bitcoin library where three fee-rate conversion functions would crash when given the maximum possible fee rate. The functions round fee rates up to different units, and internally they added a small number before dividing. When the input was the maximum value (the largest 64-bit unsigned integer), that addition overflowed and caused a panic. The fix uses saturating addition, which caps the value instead of overflowing, so the functions now return a sensible result rather than crashing.

This commit adds two optional helper methods to check whether a list of Bitcoin block headers is correctly chained and whether each header meets its own proof-of-work target. It is a defensive, non-breaking feature addition for users of the library; it does not fix an existing vulnerability or change any default behavior.

This commit is a straightforward code cleanup in the Bitcoin peer-to-peer networking code. It replaces two internal-only wrapper types with a single public type called `HeadersMessage` so that outside developers can directly serialize and deserialize lists of block headers. The actual encoding and decoding logic is unchanged; only the names and visibility are different.

This commit fixes three minor typos: one grammar correction in a code comment about SegWit transaction parsing, one grammar correction in a documentation comment about a feature flag, and one typo ('crate' to 'create') in an error message inside a test. There are no code behavior changes.

This commit removes old, deprecated functions from the rust-bitcoin `hashes` crate that were marked for removal two releases ago. It is a routine cleanup change: it deletes functions like `from_slice`, `const_hash`, and `as_u64` that users were already warned not to use, and switches internal code to use the newer replacements. There is no bug fix or security patch here.

This commit is a simple renaming cleanup. It replaces the old term 'VarInt' with 'CompactSize' in comments, variable names, error variants, and test strings. No behavior of the code changes, and no security issue is introduced or fixed.

This commit only changes documentation comments in three source files. It replaces the word 'varint' with 'CompactSize' or 'length prefix' to match the project's current terminology. No code logic, serialization, or API behavior was altered.

This commit only changes documentation comments (rustdoc) for a serialization function in the Taproot control block code. It rewords the explanation to remove the term 'varint' and clarify that the length prefix is added later when encoding as a witness element. No code logic was modified.

This is a routine automated update by Dependabot that bumps a GitHub Actions helper (used to download build artifacts) from version 4 to version 5 in a daily fuzzing workflow. There is no indication of a security problem or malicious change in the commit itself.

This commit fixes a single spelling mistake ('spilt' to 'split') in a project planning document. It does not change any code, configuration, or security behavior.

This commit is purely a code-style change. It tells the automatic formatter (rustfmt) to leave a macro call on one long line instead of spreading it across multiple lines. There is no functional change to the Bitcoin library and no security relevance.

This is a small code cleanup in the rust-bitcoin library. It replaces one style of low-level pointer casting with a more modern, equivalent Rust function. The change does not alter the actual behavior of the code; it is purely a stylistic/refactoring improvement.

This commit is a routine automated code-formatting run by the rustfmt tool. It only changes whitespace, import order, line breaks, and brace placement. There are no functional changes, bug fixes, or security-related alterations.

This commit fixes a single missing closing parenthesis in a Markdown documentation file (docs/roadmap.md). It is a typo correction with no code changes and no security relevance.
