pub fn into_message(self) -> M

Consume self returning the owned message

pub fn into_hint(self) -> Option<H>

Consume self returning the owned hint

pub fn into_message_and_hint(self) -> (M, Option<H>)

Trait Implementations

impl<M: Clone, H: Clone> Clone for Prompt<M, H>

fn clone(&self) -> Prompt<M, H>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<M: Debug, H: Debug> Debug for Prompt<M, H>

fn fmt(&self, f: &mut Formatter<'_>) -> Result
