Struct backtrace::symbolize::gimli::Cache

struct Cache {
    libraries: Vec<Library>,
    mappings: Vec<(usize, Mapping)>,
}

Fields

libraries: Vec<Library>

All known shared libraries that have been loaded.

mappings: Vec<(usize, Mapping)>

Mappings cache where we retain parsed dwarf information.

This list has a fixed capacity for its entire lifetime which never increases. The usize element of each pair is an index into libraries above where usize::max_value() represents the current executable. The Mapping is corresponding parsed dwarf information.

Note that this is basically an LRU cache and we’ll be shifting things around in here as we symbolize addresses.

Implementations

impl Cache

fn new() -> Cache

unsafe fn with_global(f: impl FnOnce(&mut Self))

fn avma_to_svma(&self, addr: *const u8) -> Option<(usize, *const u8)>

fn mapping_for_lib<'a>( &'a mut self, lib: usize ) -> Option<(&'a mut Context<'a>, &'a Stash)>

Trait Implementations

impl Default for Cache

fn default() -> Cache

Returns the “default value” for a type.
