imap-codec

This library provides parsing and serialization for [IMAP4rev1] implementations. It is based on [imap-types] and a [rock-solid] and [well-documented] building block for IMAP client and server implementations in Rust. The complete [formal syntax] of IMAP4rev1 and several IMAP [extensions] are implemented.

Features

• Parsing works in streaming mode. Incomplete is returned when there is insufficient data to make a final decision. No message will be truncated.
• Parsing is zero-copy by default. Allocation is avoided during parsing, but all messages can explicitly be converted into more flexible owned variants.
• Fuzzing and property-based tests exercise the library. The library is fuzz-tested never to produce a message it can't parse itself.

Usage

```rust use imap_codec::{ codec::{Decode, Encode}, command::Command, };

fn main() { let input = b"ABCD UID FETCH 1,2:* (BODY.PEEK[1.2.3.4.MIME]<42.1337>)\r\n";

let (remainder, parsed) = Command::decode(input).unwrap();
println!("# Parsed\n\n{:#?}\n\n", parsed);

let buffer = parsed.encode().dump();

// Note: IMAP4rev1 may produce messages that are not valid UTF-8.
println!("# Serialized\n\n{:?}", std::str::from_utf8(&buffer));

} ```
