Struct TrapReader 

pub(crate) struct TrapReader {
    source: DebugInfoSource,
}

On-demand reader of per-function trap information from an ELF artifact.

Trap lookups only happen when a trap fires, so the ELF trap sections are parsed lazily instead of duplicating all trap tables in memory.

Fields

source: DebugInfoSource

Implementations

impl TrapReader

pub(crate) fn new(source: DebugInfoSource) -> Self

pub(crate) fn lookup( &self, local_index: LocalFunctionIndex, rel_pos: u32, ) -> Option<TrapInformation>

Looks up the trap information for local_index at rel_pos, the offset relative to the start of the function.

fn lookup_in_image<'data, R: ReadRef<'data>>( image: &File<'data, R>, local_index: LocalFunctionIndex, rel_pos: u32, ) -> Option<TrapInformation>

fn parse_function_traps( traps_section: &[u8], trap_offset: usize, ) -> Option<Vec<TrapInformation>>
