Variant record info fields.

Required Methods

fn is_empty(&self) -> bool

Returns whether there are any fields.

fn len(&self) -> usize

Returns the number of fields.

fn get<'a, 'h: 'a>( &'a self, header: &'h Header, key: &str, ) -> Option<Result<Option<Value<'a>>>>

Returns the value of the given key.

fn iter<'a, 'h: 'a>( &'a self, header: &'h Header, ) -> Box<dyn Iterator<Item = Result<(&'a str, Option<Value<'a>>)>> + 'a>

Returns an iterator over fields.
