Struct DyldCache 

pub struct DyldCache {
    pub header: DyldCacheHeader,
    pub mappings: Vec<CacheMapping>,
    pub images: Vec<CacheImage>,
}

Read-only index of a dyld shared cache file.

Supports enumeration and extraction of embedded Mach-O images without modifying the cache. Extracted image slices can be fed directly into crate::format::parse for normal inspection.

Fields

header: DyldCacheHeader

The header field.

mappings: Vec<CacheMapping>

The mappings field.

images: Vec<CacheImage>

The images field.

Implementations

impl DyldCache

pub fn images(&self) -> &[CacheImage]

List all embedded images.

pub fn mappings(&self) -> &[CacheMapping]

List cache memory mappings.

pub fn arch(&self) -> &str

Architecture string extracted from the magic field.

pub fn va_to_file_offset(&self, va: u64) -> Option<u64>

Convert a virtual address to a file offset using the mapping table.

pub fn extract_image<'data>( &self, index: usize, data: &'data [u8], ) -> Result<&'data [u8]>

Extract the Mach-O bytes for the image at the given index.

Returns a slice into the original cache data that starts at the image’s mapped location. When the image has a known text_size, that is used as the slice length. Otherwise the slice extends to the next image boundary or mapping end. The returned slice can be passed to crate::format::parse.
