Struct gimli::read::DebugAbbrev

pub struct DebugAbbrev<R> { /* fields omitted */ }

The DebugAbbrev struct represents the abbreviations describing DebuggingInformationEntrys’ attribute names and forms found in the .debug_abbrev section.

Implementations

impl<'input, Endian> DebugAbbrev<EndianSlice<'input, Endian>> where
    Endian: Endianity, 

pub fn new(debug_abbrev_section: &'input [u8], endian: Endian) -> Self

Construct a new DebugAbbrev instance from the data in the .debug_abbrev section.

It is the caller’s responsibility to read the .debug_abbrev section and present it as a &[u8] slice. That means using some ELF loader on Linux, a Mach-O loader on OSX, etc.

use gimli::{DebugAbbrev, LittleEndian};

let debug_abbrev = DebugAbbrev::new(read_debug_abbrev_section_somehow(), LittleEndian);

impl<R: Reader> DebugAbbrev<R>

pub fn abbreviations(
    &self,
    debug_abbrev_offset: DebugAbbrevOffset<R::Offset>
) -> Result<Abbreviations>

Parse the abbreviations at the given offset within this .debug_abbrev section.

The offset should generally be retrieved from a unit header.

impl<T> DebugAbbrev<T>

pub fn borrow<'a, F, R>(&'a self, borrow: F) -> DebugAbbrev<R> where
    F: FnMut(&'a T) -> R, 

Create a DebugAbbrev section that references the data in self.

This is useful when R implements Reader but T does not.

Example Usage

// Read the DWARF section into a `Vec` with whatever object loader you're using.
let owned_section: gimli::DebugAbbrev<Vec<u8>> = load_section();
// Create a reference to the DWARF section.
let section = owned_section.borrow(|section| {
    gimli::EndianSlice::new(&section, gimli::LittleEndian)
});
