Build directories

cargo-mutants builds mutated code in a temporary directory, containing a copy of your source tree with each mutant successively applied. With --jobs, multiple build directories are used in parallel.

Build-in ignores

Files or directories matching these patterns are not copied:



From 23.11.2, by default, cargo-mutants will not copy files that are excluded by gitignore patterns, to make copying faster in large trees.

This behavior can be turned off with --gitignore=false.
