Enum syn::ReturnType [−][src]
This is supported on crate features
full
or derive
only.Return type of a function signature.
This type is available only if Syn is built with the "derive"
or "full"
feature.
Variants
Return type is not specified.
Functions default to ()
and closures default to type inference.
A particular type is returned.
