Struct FilterUnitEntry 

#[non_exhaustive]
pub struct FilterUnitEntry<'a, R: Reader<Offset = usize>> {
    pub read_unit: UnitRef<'a, R>,
    pub read_entry: DebuggingInformationEntry<R>,
    pub parent: Option<UnitOffset>,
    pub parent_tag: Option<DwTag>,
}

A DIE read by FilterUnit::read_entry.

This is a simple wrapper that adds some extra information to read::DebuggingInformationEntry. The inner Self::read_entry is accessible via Deref.

See FilterUnitSection for an example.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

read_unit: UnitRef<'a, R>

The unit that this DIE was read from.

This may be a skeleton unit.

read_entry: DebuggingInformationEntry<R>

The DIE that was read.

parent: Option<UnitOffset>

The offset of this DIE’s parent, if any.

This is set to None if the parent is the root of the unit.

parent_tag: Option<DwTag>

The tag of this DIE’s parent, if any.

This is set to None if the parent is the root of the unit.

Implementations

impl<'a, R: Reader<Offset = usize>> FilterUnitEntry<'a, R>

pub fn null(read_unit: UnitRef<'a, R>) -> Self

Return a null entry.

This can be used with FilterUnit::read_entry,

Methods from Deref<Target = DebuggingInformationEntry<R>>

pub fn is_null(&self) -> bool

Return true if the entry tag is DW_TAG_null.

pub fn depth(&self) -> isize

Get the tree depth of this entry relative to the entry where reading started.

pub fn offset(&self) -> UnitOffset<Offset>

Get this entry’s offset.

pub fn tag(&self) -> DwTag

Get this entry’s tag.

pub fn has_children(&self) -> bool

Return true if this entry’s type can have children, false otherwise.

pub fn attrs(&self) -> &[Attribute<R>]

Return this entry’s set of attributes.

pub fn has_attr(&self, name: DwAt) -> bool

Return true if this entry has an attribute with the given name.

pub fn attr(&self, name: DwAt) -> Option<&Attribute<R>>

Find the first attribute in this entry which has the given name.

Returns None if no attribute is found.

pub fn attr_value_raw(&self, name: DwAt) -> Option<AttributeValue<R>>

Find the first attribute in this entry which has the given name, and return its raw value.

Returns None if no attribute is found.

pub fn attr_value(&self, name: DwAt) -> Option<AttributeValue<R>>

Find the first attribute in this entry which has the given name, and return its normalized value.

Returns None if no attribute is found.

Trait Implementations

impl<'a, R: Debug + Reader<Offset = usize>> Debug for FilterUnitEntry<'a, R>

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

Formats the value using the given formatter.

impl<'a, R: Reader<Offset = usize>> Deref for FilterUnitEntry<'a, R>

type Target = DebuggingInformationEntry<R>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
