Expand description

The value of an attribute in a DebuggingInformationEntry.

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.

Exprloc(Expression<R>)

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

Flag(bool)

A boolean that indicates presence or absence of the attribute.

SecOffset(Offset)

An offset into another section. Which section this is an offset into depends on context.

DebugAddrBase(DebugAddrBase<Offset>)

An offset to a set of addresses in the .debug_addr section.

DebugAddrIndex(DebugAddrIndex<Offset>)

An index into a set of addresses in the .debug_addr section.

UnitRef(UnitOffset<Offset>)

An offset into the current compilation unit.

DebugInfoRef(DebugInfoOffset<Offset>)

An offset into the current .debug_info section, but possibly a different compilation unit from the current one.

DebugInfoRefSup(DebugInfoOffset<Offset>)

An offset into the .debug_info section of the supplementary object file.

DebugLineRef(DebugLineOffset<Offset>)

An offset into the .debug_line section.

LocationListsRef(LocationListsOffset<Offset>)

An offset into either the .debug_loc section or the .debug_loclists section.

DebugLocListsBase(DebugLocListsBase<Offset>)

An offset to a set of offsets in the .debug_loclists section.

DebugLocListsIndex(DebugLocListsIndex<Offset>)

An index into a set of offsets in the .debug_loclists section.

DebugMacinfoRef(DebugMacinfoOffset<Offset>)

An offset into the .debug_macinfo section.

DebugMacroRef(DebugMacroOffset<Offset>)

An offset into the .debug_macro section.

RangeListsRef(RawRangeListsOffset<Offset>)

An offset into the .debug_ranges section.

DebugRngListsBase(DebugRngListsBase<Offset>)

An offset to a set of offsets in the .debug_rnglists 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.

Encoding(DwAte)

The value of a DW_AT_encoding attribute.

DecimalSign(DwDs)

The value of a DW_AT_decimal_sign attribute.

The value of a DW_AT_inline attribute.

Ordering(DwOrd)

The value of a DW_AT_ordering attribute.

FileIndex(u64)

An index into the filename entries from the line number information table for the compilation unit containing this value.

DwoId(DwoId)

An implementation-defined identifier uniquely identifying a compilation unit.

Implementations

Try to convert this attribute’s value to a u8.

Try to convert this attribute’s value to a u16.

Try to convert this attribute’s value to an unsigned integer.

Try to convert this attribute’s value to a signed integer.

Try to convert this attribute’s value to an offset.

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.

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.

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.
