Well, it's possible that u8
doesn't implement Into<ContainerEnd>
it depends on what ContainerEnd
is. For example, if I wanted to call problem::<std::io::Error>()
, then I shouldn't be able to because u8
doesn't implement Into<std::io::Error>
.

Is not body explicit enough about implementing trait Into
. Does not compiler look into body on that stage of analysis?
No, Rust does not perform type inference or any other kind of inference for function signatures.
