[−][src]Enum syn::ReturnType
Return type of a function signature.
This type is available if Syn is built with the "derive"
or "full"
feature.
Variants
Default
Return type is not specified.
Functions default to ()
and closures default to type inference.
Type(RArrow, Box<Type>)
A particular type is returned.
