Struct gimli::read::DebugInfo

source ·
pub struct DebugInfo<R> { /* private fields */ }
Expand description

The DebugInfo struct represents the DWARF debugging information found in the .debug_info section.

Implementations§

source§

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

source

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

Construct a new DebugInfo instance from the data in the .debug_info section.

It is the caller’s responsibility to read the .debug_info 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::{DebugInfo, LittleEndian};

let debug_info = DebugInfo::new(read_debug_info_section_somehow(), LittleEndian);
source§

impl<R: Reader> DebugInfo<R>

source

pub fn units(&self) -> DebugInfoUnitHeadersIter<R>

Iterate the units in this .debug_info section.

use gimli::{DebugInfo, LittleEndian};

let debug_info = DebugInfo::new(read_debug_info_section_somehow(), LittleEndian);

let mut iter = debug_info.units();
while let Some(unit) = iter.next().unwrap() {
    println!("unit's length is {}", unit.unit_length());
}

Can be used with FallibleIterator.

source

pub fn header_from_offset( &self, offset: DebugInfoOffset<R::Offset>, ) -> Result<UnitHeader<R>>

Get the UnitHeader located at offset from this .debug_info section.

source§

impl<T> DebugInfo<T>

source

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

Create a DebugInfo section that references the data in self.

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

Used by DwarfSections::borrow.
