Only present when using GNU split-dwarf extension to DWARF 4.

debug_loclists: DebugLocLists<R>

The .debug_loclists.dwo section.

debug_rnglists: DebugRngLists<R>

The .debug_rnglists.dwo section.

Used when creating Dwarf<R>.

Implementations

impl<R: Reader> DwarfPackage<R>

pub fn load<F, E>(section: F, empty: R) -> Result<Self, E>

where F: FnMut(SectionId) -> Result<R, E>, E: From<Error>,

Try to load the .dwp sections using the given loader function.

section loads a DWARF section from the object file. It should return an empty section if the section does not exist.

pub fn find_cu(&self, id: DwoId, parent: &Dwarf<R>) -> Result<Option<Dwarf<R>>>

Find the compilation unit with the given DWO identifier and return its section contributions.

Example Usage

if let Some(dwo) = dwp.find_cu(dwo_id, dwarf)? {
   let dwo_header = dwo.units().next()?.expect("DWO should have one unit");
   let dwo_unit = dwo.unit(dwo_header)?;
   // Do something with `dwo_unit`.
}

pub fn find_tu( &self, signature: DebugTypeSignature, parent: &Dwarf<R>, ) -> Result<Option<Dwarf<R>>>

Find the type unit with the given type signature and return its section contributions.

pub fn cu_sections(&self, index: u32, parent: &Dwarf<R>) -> Result<Dwarf<R>>

Return the section contributions of the compilation unit at the given index.

The index must be in the range 1..cu_index.unit_count.

This function should only be needed by low level parsers.

pub fn tu_sections(&self, index: u32, parent: &Dwarf<R>) -> Result<Dwarf<R>>

Return the section contributions of the compilation unit at the given index.

The index must be in the range 1..tu_index.unit_count.

This function should only be needed by low level parsers.

pub fn sections( &self, sections: UnitIndexSectionIterator<'_, R>, parent: &Dwarf<R>, ) -> Result<Dwarf<R>>

Return the section contributions of a unit.

This function should only be needed by low level parsers.

Trait Implementations

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

Formats the value using the given formatter.
