Struct CoreDumpStackSection

pub struct CoreDumpStackSection<'a> {
    pub name: &'a str,
    pub frames: Vec<CoreDumpStackFrame>,
}

The data portion of a custom section representing a core dump stack. The structure of this follows the coredump spec in the tool-conventions repo

Examples

use wasmparser::{BinaryReader, CoreDumpStackSection, FromReader, WasmFeatures};

let data: &[u8] = &[0x00, 0x04, 0x6d, 0x61, 0x69, 0x6e, 0x01, 0x00, 0x04,
    0x2a, 0x33, 0x01, 0x7f, 0x01, 0x01, 0x7f, 0x02];
let reader = BinaryReader::new(data, 0, WasmFeatures::all());
let corestack = CoreDumpStackSection::new(reader).unwrap();
assert!(corestack.name == "main");
assert!(corestack.frames.len() == 1);
let frame = &corestack.frames[0];
assert!(frame.instanceidx == 4);
assert!(frame.funcidx == 42);
assert!(frame.codeoffset == 51);
assert!(frame.locals.len() == 1);
assert!(frame.stack.len() == 1);

Fields

name: &'a str

The thread name

frames: Vec<CoreDumpStackFrame>

The stack frames for the core dump

Implementations

impl<'a> CoreDumpStackSection<'a>

pub fn new( reader: BinaryReader<'a>, ) -> Result<CoreDumpStackSection<'a>, BinaryReaderError>

Parses this section from the provided reader, derived from a custom section.
