}
Expand description
Represents the header (not the body) of a function declaration.
Fields
inputs: &'hir [Ty<'hir>]
The types of the function’s parameters.
Additional argument data is stored in the function’s body.
output: FnRetTy<'hir>
c_variadic: bool
implicit_self: ImplicitSelfKind
Does the function have an implicit self?

Layout
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
