unwrap-as combines TryInto with unwrap.

Syntax

(unwrap-as ⟨type⟩ ⟨expr⟩)
(unwrap-as ⟨type⟩)

Semantics

  • It attempts a TryInto conversion and then unwraps the resulting Optional.
  • Use it only when failure is genuinely exceptional.
  • With one argument, it produces a unary function.

Example

(unwrap-as U16 exact-small-value)
