Variants§
Addr(u64)
“Refers to some location in the address space of the described program.”
Block(R)
A slice of an arbitrary number of bytes.
Data1(u8)
A one byte constant data value. How to interpret the byte depends on context.
From section 7 of the standard: “Depending on context, it may be a signed integer, an unsigned integer, a floating-point constant, or anything else.”
Data2(u16)
A two byte constant data value. How to interpret the bytes depends on context.
These bytes have been converted from R::Endian
. This may need to be reversed
if this was not required.
From section 7 of the standard: “Depending on context, it may be a signed integer, an unsigned integer, a floating-point constant, or anything else.”
Data4(u32)
A four byte constant data value. How to interpret the bytes depends on context.
These bytes have been converted from R::Endian
. This may need to be reversed
if this was not required.
From section 7 of the standard: “Depending on context, it may be a signed integer, an unsigned integer, a floating-point constant, or anything else.”
Data8(u64)
An eight byte constant data value. How to interpret the bytes depends on context.
These bytes have been converted from R::Endian
. This may need to be reversed
if this was not required.
From section 7 of the standard: “Depending on context, it may be a signed integer, an unsigned integer, a floating-point constant, or anything else.”
Sdata(i64)
A signed integer constant.
Udata(u64)
An unsigned integer constant.

“The information bytes contain a DWARF expression (see Section 2.5) or location description (see Section 2.6).”

section.
DebugRngListsIndex(DebugRngListsIndex<Offset>)
An index into a set of offsets in the .debug_rnglists
section.
DebugTypesRef(DebugTypeSignature)
A type signature.
DebugStrRef(DebugStrOffset<Offset>)
An offset into the .debug_str
section.
DebugStrRefSup(DebugStrOffset<Offset>)
An offset into the .debug_str
section of the supplementary object file.
DebugStrOffsetsBase(DebugStrOffsetsBase<Offset>)
An offset to a set of entries in the .debug_str_offsets
section.
DebugStrOffsetsIndex(DebugStrOffsetsIndex<Offset>)
An index into a set of entries in the .debug_str_offsets
section.
DebugLineStrRef(DebugLineStrOffset<Offset>)
An offset into the .debug_line_str
section.
String(R)
A slice of bytes representing a string. Does not include a final null byte. Not guaranteed to be UTF-8 or anything like that.

impl<R, Offset> AttributeValue<R, Offset>where
R: Reader<Offset = Offset>,
Offset: ReaderOffset,
sourcepub fn udata_value(&self) -> Option<u64>
pub fn udata_value(&self) -> Option<u64>
Try to convert this attribute’s value to an unsigned integer.
sourcepub fn sdata_value(&self) -> Option<i64>
pub fn sdata_value(&self) -> Option<i64>
Try to convert this attribute’s value to a signed integer.
sourcepub fn offset_value(&self) -> Option<R::Offset>
pub fn offset_value(&self) -> Option<R::Offset>
Try to convert this attribute’s value to an offset.
sourcepub fn exprloc_value(&self) -> Option<Expression<R>>
pub fn exprloc_value(&self) -> Option<Expression<R>>
Try to convert this attribute’s value to an expression or location buffer.
Expressions and locations may be DW_FORM_block*
or DW_FORM_exprloc
.
The standard doesn’t mention DW_FORM_block*
as a possible form, but
it is encountered in practice.
sourcepub fn string_value(&self, debug_str: &DebugStr<R>) -> Option<R>
pub fn string_value(&self, debug_str: &DebugStr<R>) -> Option<R>
Try to return this attribute’s value as a string slice.
If this attribute’s value is either an inline DW_FORM_string
string,
or a DW_FORM_strp
reference to an offset into the .debug_str
section, return the attribute’s string value as Some
. Other attribute
value forms are returned as None
.
Warning: this function does not handle all possible string forms.
Use Dwarf::attr_string
instead.
sourcepub fn string_value_sup(
&self,
debug_str: &DebugStr<R>,
debug_str_sup: Option<&DebugStr<R>>,
) -> Option<R>
pub fn string_value_sup( &self, debug_str: &DebugStr<R>, debug_str_sup: Option<&DebugStr<R>>, ) -> Option<R>
Try to return this attribute’s value as a string slice.
If this attribute’s value is either an inline DW_FORM_string
string,
or a DW_FORM_strp
reference to an offset into the .debug_str
section, or a DW_FORM_strp_sup
reference to an offset into a supplementary
object file, return the attribute’s string value as Some
. Other attribute
value forms are returned as None
.
Warning: this function does not handle all possible string forms.
Use Dwarf::attr_string
instead.
