Function enable_cache 

pub fn enable_cache() -> bool
Expand description

Enable globally cache/memoization. One can also leverage this function by setting the environment variable DYLDSC_ENABLE_CACHE to 1

By default, LIEF will use the directory specified by the environment variable DYLDSC_CACHE_DIR as its cache-root directory:

DYLDSC_ENABLE_CACHE=1 DYLDSC_CACHE_DIR=/tmp/my_dir ./my-program

Otherwise, if DYLDSC_CACHE_DIR is not set, LIEF will use the following directory (in this priority):

  1. System or user cache directory
  • macOS: DARWIN_USER_TEMP_DIR / DARWIN_USER_CACHE_DIR + /dyld_shared_cache
  • Linux: ${XDG_CACHE_HOME}/dyld_shared_cache
  • Windows: %LOCALAPPDATA%\dyld_shared_cache
  1. Home directory
  • macOS/Linux: $HOME/.dyld_shared_cache
  • Windows: %USERPROFILE%\.dyld_shared_cache

See crate::dsc::DyldSharedCache::enable_caching for a finer granularity
