Function count

pub fn count<R, T, Arg, Ret>(
    n: usize,
) -> impl Fn(&mut R, &ReadOptions, Arg) -> BinResult<Ret>
where
    T: BinRead<Args = Arg>,
    R: Read + Seek,
    Arg: Clone,
    Ret: FromIterator<T>,

A helper equivelant to #[br(count = N)] which can be used with any collection.

Examples

#[derive(BinRead)]
struct CountBytes {
    len: u8,

    #[br(parse_with = count(len as usize))]
    data: Vec<u8>,
}
