Enum GenericValue 

pub enum GenericValue {
    Ty(Ty),
    Expr(Expr),
    Lifetime,
}

Represents a generic value used in type applications (e.g., T in Vec<T>).

Variants

Ty(Ty)

A type-level generic value.

Example:

i32 in Vec<i32>

Expr(Expr)

A const-level generic value.

Example:

12 in Foo<12>

Lifetime

A lifetime.

Example:

'a in foo<'a>

Implementations

impl GenericValue

pub fn expect_ty(&self) -> Option<&Ty>
