Implementations§

source§

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

source

pub fn u8_value(&self) -> Option<u8>

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

source

pub fn u16_value(&self) -> Option<u16>

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

source

pub fn udata_value(&self) -> Option<u64>

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

source

pub fn sdata_value(&self) -> Option<i64>

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

source

pub fn offset_value(&self) -> Option<R::Offset>

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

source

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.

source

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.

source

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.
