Expand description

Extension trait for reading tags from Read instances.

This trait provides a convenient method to read tags directly from any type that implements std::io::Read.

§Example

use ::std::io::Cursor;
use ::protobuf_core::ReadExtTag;

let data = vec![0x08]; // tag 1:0 (field 1, wire type 0)
let mut reader = Cursor::new(data);
let tag = reader.read_tag().unwrap().unwrap();
assert_eq!(tag.field_number.as_u32(), 1);
