Exclude mutating `ExactSizeEncoder::is_empty`
Encoder tests has been updated to test the outcome of encoders, and
not the internal details of the encoder, this is a default method
which is too trivial to test.
What changed, and why it matters
This commit only updates a configuration file used by an automated mutation-testing tool. It tells the tool not to waste time trying to mutate a very simple default method called `is_empty` on an encoder type. There is no change to actual library code, no bug fix, and no security relevance.
No action needed; this is a testing-tool configuration change with no security or functional impact.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff adds one line to .cargo/mutants.toml, an exclusion list for cargo-mutants. The new regex consensus_encoding/.* ExactSizeEncoder::is_empty prevents the mutation tester from generating mutants for the trivial is_empty default implementation. No Rust source code is modified, no behavior changes, and no vulnerability is addressed.
