Struct ink_metadata::TypeSpec
source · pub struct TypeSpec<F: Form = MetaForm> { /* private fields */ }
Expand description
A type specification.
This contains the actual type as well as an optional compile-time known displayed representation of the type. This is useful for cases where the type is used through a type alias in order to provide information about the alias name.
Examples
Consider the following Rust function:
fn is_sorted(input: &[i32], pred: Predicate) -> bool;
In this above example input
would have no displayable name,
pred
s display name is Predicate
and the display name of
the return type is simply bool
. Note that Predicate
could
simply be a type alias to fn(i32, i32) -> Ordering
.
