Add mutation excludes for impl encoding::Decoder
The min_byte_needed function is a simple cast for optimization and does
not need to be tested.
Add a mutation testing exclude for all of these functions.
What changed, and why it matters
This commit only updates a mutation testing configuration file. It tells the mutation testing tool not to bother testing certain simple functions that are just type casts for performance reasons. There is no code change, no bug fix, and no security relevance.
No action needed. This is a testing configuration change with no security implications.
Security signals we found
No strong security signals were identified.
