Struct gimli::read::EhFrame

source ·
pub struct EhFrame<R: Reader> { /* private fields */ }
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§

source§

impl<R: Reader> EhFrame<R>

source

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.

source

pub fn set_vendor(&mut self, vendor: Vendor)

Set the vendor extensions to use.

This defaults to Vendor::Default.

source§

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

source

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

Construct a new EhFrame instance from the data in the .eh_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 macOS, etc.

use gimli::{EhFrame, EndianSlice, NativeEndian};

// Use with `.eh_frame`
let eh_frame = EhFrame::new(read_eh_frame_section_somehow(), NativeEndian);
