}

A function or public symbol.

Fields

addr_low: u32

Low bits of the address.

addr_high: u16

High bits of the address.

len: u16

The length of the function.

line_records: Seg<LineRecord, u16>

The line record of this function. If it fully overlaps with an inline the record could be ~0.

comp_dir: Seg<u8, u8>

The comp dir of the file record.

parent_offset: u16

The ID offset of the parent funciton. Will be ~0 if the function has no parent.

symbol_id_low: u16

The low bits of the ID of the symbol of this function or ~0 if no symbol.

symbol_id_high: u8

The high bits of the ID of the symbol of this function or ~0 if no symbol.

lang: u8

The language of the func record.

Methods

impl FuncRecord

pub fn symbol_id(&self) -> u32

An index into the symbols segment for the function/symbol name.

pub fn addr_start(&self) -> u64

The start instruction address address of the function.

pub fn addr_end(&self) -> u64

The instruction address after the end of the function.

pub fn addr_in_range(&self, addr: u64) -> bool

Checks whether the given address is covered by the function.

pub fn parent(&self, func_id: usize) -> Option<usize>

Resolves the index of the parent function in the functions segment, if this is an inlined function.
