Struct FrameTable 

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

A parser for a frame-table section.

This parser holds slices to the in-memory section data, and is cheap to construct: it reads some header fields but does not interpret or validate content data until queried.

Implementations

impl<'a> FrameTable<'a>

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

Parse a frame table section from a byte-slice as produced by [crate::compile::frame_table::FrameTableBuilder].

pub fn frame_descriptor( &self, frame_descriptor: FrameTableDescriptorIndex, ) -> Option<(&'a [u8], u32)>

Get raw frame descriptor data and slot-to-FP-offset for a given frame descriptor.

pub fn find_program_point( &self, search_pc: u32, search_pos: FrameInstPos, ) -> Option<impl Iterator<Item = (u32, FrameTableDescriptorIndex, FrameStackShape)>>

Get frames for the program point at the PC upper-bounded by a given search PC (offset in text section).

pub fn into_program_points( self, ) -> impl Iterator<Item = (u32, FrameInstPos, Vec<(u32, FrameTableDescriptorIndex, FrameStackShape)>)> + 'a

Get all program point records with iterators over corresponding frames for each.
