Enum syn::FnArg [−][src]
An argument in a function signature: the n: usize
in fn f(n: usize)
.
This type is available only if Syn is built with the "full"
feature.
Variants
Receiver(Receiver)
The self
argument of an associated method, whether taken by value
or by reference.
Note that self
receivers with a specified type, such as self: Box<Self>
, are parsed as a FnArg::Typed
.
Typed(PatType)
A function argument accepted by pattern and type.
