-
-imap-proto is a low-level IMAP protocol support crate, using the type system to
-provide a safe API.
-
-Protocol support is implemented in three parts:
-
-* Types that attempt to closely reflect specification requirements
-* A parser implementation to help consume protocol messages
-* Builder types to help produce protocol messages
-
-imap-proto was initially started as part of [tokio-imap][tokio-imap].
-It was moved into a separate crate so that different protocol implementations
-can share it as common infrastructure (as proposed by [rust-imap][rust-imap] contributors).
-The code tries to closely follow the [IMAP4rev1 RFC][rfc3501], plus extensions.
-
-All feedback welcome. Feel free to file bugs, requests for documentation and
-any other feedback in the [issue tracker][issues], or [tweet me][twitter].
