Crate webext [−] [src]
A library to make native messaging even easier than it already is.
Typically you'd use this in a loop, reading a message in and writing a message out until there are none left to read. Perhaps something like this:
#[derive(Deserialize)] struct Input { n: usize } #[derive(Serialize)] struct Output { n: usize } // An extension that just adds one to the input number `n`. while let Some(msg) = webext::read::<Input>() { let inp = msg.unwrap(); let out = Output { n: inp.n + 1 }; webext::write(&out).unwrap(); }
Serde
I strongly recommend that you use this with serde_derive
so that you can
use your own structs for input and output. Alternatively, you can use the
Json
type, but that's a lot more annoying to deal with. My favorite enum
attributes are #[serde(tag = "type", rename_all = "snake_case")]
.
