Struct DebuggingInformationEntry 

pub struct DebuggingInformationEntry<R, Offset = <R as Reader>::Offset>
where
    R: Reader<Offset = Offset>,
    Offset: ReaderOffset,
{
    pub tag: DwTag,
    pub has_children: bool,
    pub attrs: Vec<Attribute<R>>,
    pub offset: UnitOffset<Offset>,
    pub depth: isize,
}

A Debugging Information Entry (DIE).

DIEs have a set of attributes and optionally have children DIEs as well.

Creating a DebuggingInformationEntry requires an allocation, so frequent cloning of this struct may be slow.

Fields

tag: DwTag

The DWARF tag for this entry.

has_children: bool

Whether this entry has a null terminated list of children.

Note that this list may be empty.

attrs: Vec<Attribute<R>>

This entry’s attributes.

offset: UnitOffset<Offset>

The offset within the unit of this entry.

depth: isize

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

Implementations

impl<R, Offset> DebuggingInformationEntry<R, Offset>

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

pub fn new( tag: DwTag, has_children: bool, attrs: Vec<Attribute<R>>, offset: UnitOffset<Offset>, ) -> Self

Construct a new DebuggingInformationEntry.

pub fn null() -> Self

Construct a new DebuggingInformationEntry with no tag or attributes.

pub fn is_null(&self) -> bool

Return true if the entry tag is DW_TAG_null.

pub fn set_null(&mut self)

Set the entry to a null entry.

This sets the tag to DW_TAG_null, and resets the has_children and attrs fields.

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<R, Offset> Clone for DebuggingInformationEntry<R, Offset>

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

fn clone(&self) -> DebuggingInformationEntry<R, Offset>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<R, Offset> Debug for DebuggingInformationEntry<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.

impl<R, Offset> Default for DebuggingInformationEntry<R, Offset>

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

fn default() -> Self

Returns the “default value” for a type.
