Hi List,
Using serialize crate, I have made a typo in attribute name and wrote
'derives' instead of 'deriving' and I got an error message about
`ToJson` trait not being implemented.
Here is what I did:
> cat foo.rs
extern crate serialize;
use serialize::json;
#[derive(Decodable, Encodable)]
pub struct Data {
test: bool,
uuid: int,
time: f64,
}
fn main() {
let data = Data { test: true, uuid: 123, time: 34349480.24 };
json::encode(&data);
}
> rustc foo.rs
foo.rs:13:3: 13:15 error: failed to find an implementation of trait
serialize::serialize::Encodable<serialize::json::Encoder<'_>,std::io::IoError>
for Data
foo.rs:13 json::encode(&data);
^~~~~~~~~~~~
The compiler happily skipped over unknown attribute... Is this a
desired behaviour or a known issues?
Cheers,
