Trait DecodeWithLength 

pub trait DecodeWithLength {
    // Required method
    fn decode_with_len(
        data: &mut &[u8],
        len: usize,
    ) -> Result<Self, DecodeError>
       where Self: Sized;
}

A type that can be decoded from a sequence of bytes, given an indicator of the number of items contained within the type.

This is primarily intended for collection-like types (e.g. Vec) whose number of elements must be known before decoding can proceed. The caller provides len as the number of items expected to be decoded.

Like Decode, the input slice will be advanced by the number of bytes successfully consumed.

Required Methods

fn decode_with_len(data: &mut &[u8], len: usize) -> Result<Self, DecodeError>

where Self: Sized,

Attempts to decode Self from the provided byte slice, consuming exactly len items.

On success, returns the decoded value and advances data by the number of bytes consumed. On failure, returns a DecodeError.

Errors

Returns a DecodeError if the input is malformed or insufficient to decode a complete value of this type.
