Struct gimli::read::EhFrame

[+] Show declaration

pub struct EhFrame<R: Reader> { /* fields omitted */ }

[−] Expand description

EhFrame contains the frame unwinding information needed during exception handling found in the .eh_frame section.

Most interesting methods are defined in the UnwindSection trait.

See DebugFrame for some discussion on the differences between .debug_frame and .eh_frame.

Implementations

impl<R: Reader> EhFrame<R>[−]

pub fn set_address_size(&mut self, address_size: u8)[−]

Set the size of a target address in bytes.

This defaults to the native word size.

impl<'input, Endian> EhFrame<EndianSlice<'input, Endian>> where
    Endian: Endianity, [−]

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

Construct a new EhFrame instance from the data in the .debug_frame section.

It is the caller's responsibility to read the 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::{EhFrame, EndianSlice, NativeEndian};

// Use with `.debug_frame`
let debug_frame = EhFrame::new(read_debug_frame_section_somehow(), NativeEndian);
