Struct gimli::read::AttrsIter

pub struct AttrsIter<'abbrev, 'entry, 'unit, R: Reader> { /* fields omitted */ }

An iterator over a particular entry's attributes.

See the documentation for DebuggingInformationEntry::attrs() for details.

Can be used with FallibleIterator.

Implementations

impl<'abbrev, 'entry, 'unit, R: Reader> AttrsIter<'abbrev, 'entry, 'unit, R>

pub fn next(&mut self) -> Result<Option<Attribute<R>>>

Advance the iterator and return the next attribute.

Returns None when iteration is finished. If an error occurs while parsing the next attribute, then this error is returned, and all subsequent calls return None.
