Struct gimli::read::DebugTypes

pub struct DebugTypes<R> { /* private fields */ }

The DebugTypes struct represents the DWARF type information found in the .debug_types section.

Implementations

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

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

Construct a new DebugTypes instance from the data in the .debug_types section.

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

let debug_types = DebugTypes::new(read_debug_types_section_somehow(), LittleEndian);

impl<T> DebugTypes<T>

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

Create a DebugTypes 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::DebugTypes<Vec<u8>> = load_section();
// Create a reference to the DWARF section.
let section = owned_section.borrow(|section| {
    gimli::EndianSlice::new(&section, gimli::LittleEndian)
});

impl<R: Reader> DebugTypes<R>

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

Iterate the type-units in this .debug_types section.

use gimli::{DebugTypes, LittleEndian};

let debug_types = DebugTypes::new(read_debug_types_section_somehow(), LittleEndian);

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

Can be used with FallibleIterator.
