Struct lief::dsc::dyld_shared_cache::DyldSharedCache
pub struct DyldSharedCache { /* private fields */ }Expand description
This struct interfaces a dyld shared cache file.
Implementations§
pub fn filename(&self) -> String
pub fn filename(&self) -> String
Filename of the dyld shared file associated with this object.
For instance: dyld_shared_cache_arm64e, dyld_shared_cache_arm64e.62.dyldlinkedit
pub fn filepath(&self) -> String
pub fn filepath(&self) -> String
Full path to the original dyld shared cache file associated with object
(e.g. /home/lief/downloads/visionos/dyld_shared_cache_arm64e.42)
pub fn load_address(&self) -> u64
pub fn load_address(&self) -> u64
Based address of this cache
pub fn find_lib_from_va(&self, va: u64) -> Option<Dylib<'_>>
pub fn find_lib_from_va(&self, va: u64) -> Option<Dylib<'_>>
Find the Dylib that encompasses the given virtual address.
pub fn find_lib_from_path(&self, path: &str) -> Option<Dylib<'_>>
pub fn find_lib_from_path(&self, path: &str) -> Option<Dylib<'_>>
Find the Dylib whose Dylib::path matches the provided path.
pub fn find_lib_from_name(&self, name: &str) -> Option<Dylib<'_>>
pub fn find_lib_from_name(&self, name: &str) -> Option<Dylib<'_>>
Find the Dylib whose filename of Dylib::path matches the provided name.
If multiple libraries have the same name (but with a different path), the first one matching the provided name is returned.
pub fn has_subcaches(&self) -> bool
pub fn has_subcaches(&self) -> bool
True if the subcaches are associated with this cache
pub fn libraries(&self) -> Dylibs<'_> ⓘ
pub fn libraries(&self) -> Dylibs<'_> ⓘ
Return an iterator over the different Dylib libraries embedded
in this dyld shared cache
pub fn mapping_info(&self) -> MappingInfoIt<'_> ⓘ
pub fn mapping_info(&self) -> MappingInfoIt<'_> ⓘ
Return an iterator over the different MappingInfo associated
with this dyld shared cache
pub fn subcaches(&self) -> SubCacheIt<'_> ⓘ
pub fn subcaches(&self) -> SubCacheIt<'_> ⓘ
Return an interator over the subcaches associated with this (main) dyld shared cache.
pub fn enable_caching(&self, target_cache_dir: &str)
pub fn enable_caching(&self, target_cache_dir: &str)
When enabled, this function allows to record and to keep in cache, dyld shared cache information that are costly to access.
For instance, GOT symbols, rebases information, stub symbols, …
It is highly recommended to enable this function when processing
a dyld shared cache several times or when extracting a large number of
Dylib with enhanced extraction options (e.g. crate::dsc::dylib::ExtractOpt::fix_memory)
One can enable caching by calling this function:
let dyld_cache = lief::dsc::load_from_path("macos-15.0.1/", "");
dyld_cache.enable_caching("/home/user/.cache/lief-dsc");One can also enable this cache optimization globally using the
function: crate::dsc::enable_cache or by setting the environment variable
DYLDSC_ENABLE_CACHE to 1.
pub fn flush_cache(&self)
pub fn flush_cache(&self)
Flush internal information into the on-disk cache (see: enable_caching)
