I try to develop a function that take a Encodable parameter but I have
the error wrong number of type arguments: expected 1 but found 0
pub fn memory_encode(to_encode_object: &serialize::Encodable) -> @mut
MemWriter {
//Serialize the object in a string using a writer
let m = @mut MemWriter::new();
let mut encoder = Encoder(m as @mut Writer);
to_encode_object.encode(&mut encoder);
m
}
The encodable trait is :
pub trait Encodable<S:Encoder> {
fn encode(&self, s: &mut S);
}
I try this definition
memory_encode<T:serialize::Encodable<Encoder>>(to_encode_object: &T) ->
@mut MemWriter
But I can't use the method with a struct that implement Encodable. The
error : mismatched types: expected `&<V31>` but found ..
I have another question :
I would like to return a MemWriter and not a @mut MemWriter . I didn't
find a way to convert the @mut to ~
