Struct MessageSlicer

pub struct MessageSlicer<'de> { /* private fields */ }

MessageSlicer wraps a Slicer to provide:

1. Methods to parse fields because we already know the fixed length of those fields.
2. A validated input. We know a Message must be a minimum length because we know the size of certain fields. This allows us to use faster unchecked parsing if we check the length at instantiation.

MessageSlicer is useful to implement from_bytes from DecodeMessage.
