Expand description

Checked values.

Associated Types

type Ok

The value returned when the check passes.

This will often be Self, but it’s specified as an associated type to allow for information to be lost from the checked value.

type Err

The error returned when the check fails.

fn check(self) -> Result<Self::Ok, Self::Err>

Check self.

If self is valid this should return Ok(Self::Ok), and otherwise Err(Self::Err).
