Fields

header: UnitHeader<R, Offset>

The header of the unit.

abbreviations: Arc<Abbreviations>

The parsed abbreviations for the unit.

name: Option<R>

The DW_AT_name attribute of the unit.

comp_dir: Option<R>

The DW_AT_comp_dir attribute of the unit.

low_pc: u64

The DW_AT_low_pc attribute of the unit. Defaults to 0.

str_offsets_base: DebugStrOffsetsBase<Offset>

The DW_AT_str_offsets_base attribute of the unit. Defaults to 0.

addr_base: DebugAddrBase<Offset>

The DW_AT_addr_base attribute of the unit. Defaults to 0.

loclists_base: DebugLocListsBase<Offset>

The DW_AT_loclists_base attribute of the unit. Defaults to 0.

rnglists_base: DebugRngListsBase<Offset>

The DW_AT_rnglists_base attribute of the unit. Defaults to 0.

line_program: Option<IncompleteLineProgram<R, Offset>>

The line number program of the unit.

dwo_id: Option<DwoId>

The DWO ID of a skeleton unit or split compilation unit.

Implementations

impl<R: Reader> Unit<R>

pub fn new(dwarf: &Dwarf<R>, header: UnitHeader<R>) -> Result<Self>

Construct a new Unit from the given unit header.

pub fn new_with_abbreviations( dwarf: &Dwarf<R>, header: UnitHeader<R>, abbreviations: Arc<Abbreviations>, ) -> Result<Self>

Construct a new Unit from the given unit header and abbreviations.

The abbreviations for this call can be obtained using dwarf.abbreviations(&header). The caller may implement caching to reuse the Abbreviations across units with the same header.debug_abbrev_offset() value.

pub fn unit_ref<'a>(&'a self, dwarf: &'a Dwarf<R>) -> UnitRef<'a, R>

Return a reference to this unit and its associated Dwarf.

pub fn encoding(&self) -> Encoding

Return the encoding parameters for this unit.

pub fn entry( &self, offset: UnitOffset<R::Offset>, ) -> Result<DebuggingInformationEntry<'_, '_, R>>

Read the DebuggingInformationEntry at the given offset.

pub fn entries(&self) -> EntriesCursor<'_, '_, R>

Navigate this unit’s DebuggingInformationEntrys.

pub fn entries_at_offset( &self, offset: UnitOffset<R::Offset>, ) -> Result<EntriesCursor<'_, '_, R>>

Navigate this unit’s DebuggingInformationEntrys starting at the given offset.

pub fn entries_tree( &self, offset: Option<UnitOffset<R::Offset>>, ) -> Result<EntriesTree<'_, '_, R>>

Navigate this unit’s DebuggingInformationEntrys as a tree starting at the given offset.

pub fn entries_raw( &self, offset: Option<UnitOffset<R::Offset>>, ) -> Result<EntriesRaw<'_, '_, R>>

Read the raw data that defines the Debugging Information Entries.

pub fn copy_relocated_attributes(&mut self, other: &Unit<R>)

Copy attributes that are subject to relocation from another unit. This is intended to be used to copy attributes from a skeleton compilation unit to the corresponding split compilation unit.

pub fn dwo_name(&self) -> Result<Option<AttributeValue<R>>>

Find the dwo name (if any) for this unit, automatically handling the differences between the standardized DWARF 5 split DWARF format and the pre-DWARF 5 GNU extension.

The returned value is relative to this unit’s comp_dir.

Trait Implementations

impl<R, Offset> Debug for Unit<R, Offset>

where R: Reader<Offset = Offset> + Debug, Offset: ReaderOffset + Debug,

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

Formats the value using the given formatter.
