Struct gimli::EhFrame

pub struct EhFrame<R: Reader>(_);

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.

Methods

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);

Trait Implementations
