Function parse_fixed_header 

pub fn parse_fixed_header(
    stream: Iter<'_, u8>,
) -> Result<ParsedFixedHeader, Error>

Parses the fixed header from the provided iterator.

Errors

Returns an error when the header is incomplete or the remaining length field is malformed.

Panics

Panics only if the iterator yields fewer than two bytes after the explicit length check above, which would indicate a broken iterator implementation.
