Implementations

impl<T> Choice<T>

pub fn map<U, F: FnOnce(T) -> U>(self, f: F) -> Choice<U>

Maps an Choice<T> to Choice<U> by applying a function to the contained Choice::Choice if any.

pub fn is_choice(&self) -> bool

Returns true if the choice is a Choice::Choice.

pub fn is_separator(&self) -> bool

Returns true if the choice is a separator.

pub fn as_ref(&self) -> Choice<&T>

Converts &Choice<T> to Choice<&T>.

This will clone the Choice::Separator if any.

pub fn as_mut(&mut self) -> Choice<&mut T>

Converts &mut Choice<T> to Choice<&mut T>.

This will clone the Choice::Separator if any.

pub fn unwrap_choice(self) -> T

Returns the contained Choice::Choice value, consuming self.

Panics

This will panic if self is not a Choice::Choice.
