Std.Result.unwrapOr

1 declaration

fn

unwrapOr: Result[T, E] -> T -> T

This is a callable function.

What it does

The value, or a fallback when the operation failed.

The failure is discarded, which is why this is the only form that takes one:

a caller who needs to know why should match, or propagate with `?`.

Read the signature

  • The text after the name is the type checked by Pudu.
  • Read arrows from left to right: inputs come first, and the final type is returned.
  • Names inside [ ] are type arguments, such as the item type held by a collection.
  • Result makes success and recoverable failure part of the function's type.
