Trait argdata::Seq

pub trait Seq<'d> {
    fn iter_seq_next<'a>(
        &'a self, 
        cookie: &mut usize
    ) -> Option<Result<ArgdataRef<'a, 'd>, ReadError>>
    where
        'd: 'a;
}

An argdata value representing a sequence.

Required Methods

fn iter_seq_next<'a>(
    &'a self,
    cookie: &mut usize
) -> Option<Result<ArgdataRef<'a, 'd>, ReadError>> where
    'd: 'a, 

Iterate to the next element, returning None if the end is reached.

You probably want to use iter_seq instead, which gives you a normal Iterator.

cookie should be 0 for the first element, and is modified by this method to refer to the next element on each call. The value of the cookie is implementation-specific. It might for example be the index into a vector, or the byte-offset into an encoded argdata value.

Might panic if you give it an invalid cookie.

Methods

impl<'a, 'd: 'a> Seq<'d> + 'a

Important traits for SeqIterator<'a, 'd>

impl<'a, 'd: 'a> Iterator for SeqIterator<'a, 'd> type Item = Result<ArgdataRef<'a, 'd>, ReadError>;

pub fn iter_seq(&'a self) -> SeqIterator<'a, 'd>

Get an iterator to the elements of the sequence.
