Struct gimli::EhHdrTable

pub struct EhHdrTable<'a, R: Reader + 'a> { /* fields omitted */ }

The CFI binary search table that is an optional part of the .eh_frame_hdr section.

Methods

impl<'a, R: Reader + 'a> EhHdrTable<'a, R>

pub fn lookup(&self, address: u64, bases: &BaseAddresses) -> Result<Pointer>

Probably returns a pointer to the FDE for the given address.

This performs a binary search, so if there is no FDE for the given address, this function will return a pointer to any other FDE that's close by.

To be sure, you must call contains on the FDE.

pub fn lookup_and_parse<F>(     &self,     address: u64,     bases: &BaseAddresses,     frame: EhFrame<R>,     cb: F ) -> Result<FrameDescriptionEntry<EhFrame<R>, R, R::Offset>> where     F: FnMut(EhFrameOffset<R::Offset>) -> Result<CommonInformationEntry<EhFrame<R>, R, R::Offset>>,

Returns a parsed FDE for the given address, or NoUnwindInfoForAddress if there are none.

You must provide a function get its associated CIE. See PartialFrameDescriptionEntry::parse for more information.

Example

let table = eh_frame_hdr.table().unwrap();
let fde = table.lookup_and_parse(addr, &bases, eh_frame.clone(),
    |offset| eh_frame.cie_from_offset(&bases, offset))?;
