struct DwarfCache {
contexts: HashMap<String, Option<Context<EndianSlice<'static, RunTimeEndian>>>>,
}Expand description
Cache of addr2line contexts, keyed by library path.
Library bytes are leaked to get a 'static lifetime for gimli’s
EndianSlice. This is bounded by the number of unique .so files
loaded per session (typically < 20).
Fields§
§contexts: HashMap<String, Option<Context<EndianSlice<'static, RunTimeEndian>>>>Map from library path → addr2line Context (or None if DWARF unavailable).
Implementations§
Source§impl DwarfCache
impl DwarfCache
fn new() -> Self
Sourcefn get_context(
&mut self,
library_path: &str,
) -> Option<&Context<EndianSlice<'static, RunTimeEndian>>>
fn get_context( &mut self, library_path: &str, ) -> Option<&Context<EndianSlice<'static, RunTimeEndian>>>
Get or create an addr2line Context for the given library path.
Sourcefn load_context(
library_path: &str,
) -> Option<Context<EndianSlice<'static, RunTimeEndian>>>
fn load_context( library_path: &str, ) -> Option<Context<EndianSlice<'static, RunTimeEndian>>>
Try to load DWARF debug info from a shared library. Uses platform-specific discovery to find debug info in dSYM bundles, .gnu_debuglink targets, build-id paths, or the binary itself.
