Struct gimli::DebugLine [] [src]

pub struct DebugLine<'input, Endian> where Endian: Endianity { /* fields omitted */ }

The DebugLine struct contains the source location to instruction mapping found in the .debug_line section.

Methods

impl<'input, Endian> DebugLine<'input, Endian> where Endian: Endianity
[src]

Construct a new DebugLine instance from the data in the .debug_line section.

It is the caller's responsibility to read the .debug_line 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::{DebugLine, LittleEndian};

let debug_line = DebugLine::<LittleEndian>::new(read_debug_line_section_somehow());

Parse the line number program header at the given offset in the .debug_line section.

The address_size must match the compilation unit that the lines apply to. The comp_dir should be from the DW_AT_comp_dir attribute of the compilation unit. The comp_name should be from the DW_AT_name attribute of the compilation unit.

use gimli::{DebugLine, DebugLineOffset, LineNumberProgramHeader, LittleEndian};

let debug_line = DebugLine::<LittleEndian>::new(read_debug_line_section_somehow());

// In a real example, we'd grab the offset via a compilation unit
// entry's `DW_AT_stmt_list` attribute, and the address size from that
// unit directly.
let offset = DebugLineOffset(0);
let address_size = 8;

let header = debug_line.header(offset, address_size, None, None)
    .expect("should have found a header at that offset, and parsed it OK");
