Enum Command

pub enum Command<R, T> {
    Give(T),
    Return(R),
    Break,
    Continue,
}

A deferred control-flow command.

Variants

Give(T)

Pass the value on.

This is not the same as return. What it does is that instead of breaking the control flow, it passes on the value. That is, when run!() is called on this variant, the value that it holds is evaluated to.

Return(R)

Return the value.

This (when eventually executed) returns the given value.

Break

Break a loop.

This (when eventually executed) breaks the loop.

Continue

Continue a loop.

This (when eventually executed) continues the loop to next iteration.
