Struct ExceptionTable 

pub struct ExceptionTable<'a> { /* private fields */ }

ExceptionTable deserialized from a serialized slice.

This struct retains borrows of the various serialized parts of the exception table data as produced by ExceptionTableBuilder::serialize.

Implementations

impl<'a> ExceptionTable<'a>

pub fn parse(data: &'a [u8]) -> Result<ExceptionTable<'a>>

Parse exception tables from a byte-slice as produced by ExceptionTableBuilder::serialize.

pub fn lookup(&self, pc: u32, tag: u32) -> Option<u32>

Look up the handler destination, if any, for a given return address (as an offset into the code section) and exception tag.

Note: we use raw u32 types for code offsets and tags here to avoid dependencies on cranelift-codegen when this crate is built without compiler backend support (runtime-only config).

Trait Implementations

impl<'a> Clone for ExceptionTable<'a>

fn clone(&self) -> ExceptionTable<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for ExceptionTable<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
