Enum Bound 

pub enum Bound {
    Unbounded,
    Const(Id<ConstExprNode>),
}

Collection bound.

Retains the expression, not only its value, so the declaration can be rendered back to source. Spec §3.2.

Variants

Unbounded

No bound.

Const(Id<ConstExprNode>)

Bounded by a constant expression.

Implementations

impl Bound

pub const fn expr(self) -> Option<Id<ConstExprNode>>

pub const fn is_bounded(self) -> bool

Whether the collection is bounded.
