Struct gimli::DebuggingInformationEntry

pub struct DebuggingInformationEntry<'input, 'abbrev, 'unit, Endian> where 'input: 'unit, Endian: Endianity + 'unit {
    // some fields omitted
}

A Debugging Information Entry (DIE).

DIEs have a set of attributes and optionally have children DIEs as well.

Methods

impl<'input, 'abbrev, 'unit, Endian> DebuggingInformationEntry<'input, 'abbrev, 'unit, Endian> where Endian: Endianity

fn code(&self) -> u64

Get this entry's code.

fn offset(&self) -> usize

Get this entry's offset.

fn tag(&self) -> DwTag

Get this entry's DW_TAG_whatever tag.

let entry = get_some_entry();

match entry.tag() {
    gimli::DW_TAG_subprogram =>
        println!("this entry contains debug info about a function"),
    gimli::DW_TAG_inlined_subroutine =>
        println!("this entry contains debug info about a particular instance of inlining"),
    gimli::DW_TAG_variable =>
        println!("this entry contains debug info about a local variable"),
    gimli::DW_TAG_formal_parameter =>
        println!("this entry contains debug info about a function parameter"),
    otherwise =>
        println!("this entry is some other kind of data: {:?}", otherwise),
};

fn attrs<'me>(&'me self) -> AttrsIter<'input, 'abbrev, 'me, 'unit, Endian>

Iterate over this entry's set of attributes.

use gimli::{DebugAbbrev, DebugInfo, LittleEndian};

// Read the `.debug_info` section.

let debug_info = DebugInfo::<LittleEndian>::new(read_debug_info_section_somehow());

// Get the data about the first compilation unit out of the `.debug_info`.

let unit = debug_info.units().next()
    .expect("Should have at least one compilation unit")
    .expect("and it should parse ok");

// Read the `.debug_abbrev` section and parse the
// abbreviations for our compilation unit.

let debug_abbrev = DebugAbbrev::<LittleEndian>::new(read_debug_abbrev_section_somehow());
let abbrevs = unit.abbreviations(debug_abbrev).unwrap();

// Get the first entry from that compilation unit.

let mut cursor = unit.entries(&abbrevs);
let (_, entry) = cursor.next_dfs()
    .expect("Should parse next entry")
    .expect("Should have at least one entry");

// Finally, print the first entry's attributes.

let mut attrs = entry.attrs();
while let Some(attr) = attrs.next().unwrap() {
    println!("Attribute name = {:?}", attr.name());
    println!("Attribute value = {:?}", attr.value());
}

fn attr_value(&self, name: DwAt) -> Option<AttributeValue<'input>>

Find the first attribute in this entry which has the given name, and return its value. Returns Ok(None) if no attribute is found.
