Struct ExactVecDecoderWith 

pub struct ExactVecDecoderWith<D: Decoder + Default> { /* private fields */ }

A decoder for a vector of exactly count items, where the count is known at construction.

Use this when the item count is determined by context (e.g. from a previously decoded transaction) rather than from a length prefix in the byte stream. For the length-prefixed case, use VecDecoderWith.
