Function addDirectoryWatchInput [src]

Any changes inside the directory will trigger invalidation. See also addDirectoryWatchInputFromPath which takes a Build.Cache.Path instead. Paths derived from this directory should also be manually added via addDirectoryWatchInputFromPath if and only if this function returns true.

Prototype

pub fn addDirectoryWatchInput(step: *Step, lazy_directory: Build.LazyPath) Allocator.Error!bool

Parameters

step: *Steplazy_directory: Build.LazyPath
