Struct dialectic::types::Choose

#[repr(transparent)]pub struct Choose<Choices>(pub Choices);

Actively choose between any of the protocols in the tuple Choices.

At most 128 choices can be presented to a Choose type; to choose from more options, nest Chooses within each other.

Trait Implementations

impl<E, Choices: Any> Actionable<E> for Choose<Choices> where
    Choices: Tuple,
    Choices::AsList: EachSession,
    <Choices::AsList as EachSession>::Dual: List + EachSession,
    Choices::AsList: EachScoped<E::Depth>,
    E: Environment, 

type Action = Choose<Choices>

type Env = E

The environment resulting from stepping through one or many Loop, Break, or Continue points to the next real channel action.

pub fn partial_cmp(&self, other: &Choose<Choices>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

pub fn lt(&self, other: &Choose<Choices>) -> bool

This method tests less than (for self and other) and is used by the < operator.

pub fn le(&self, other: &Choose<Choices>) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

pub fn gt(&self, other: &Choose<Choices>) -> bool

This method tests greater than (for self and other) and is used by the > operator.

pub fn ge(&self, other: &Choose<Choices>) -> bool

impl<N: Unary, Choices: Tuple + Any> Scoped<N> for Choose<Choices> where
    Choices::AsList: EachScoped<N>,
    <Choices::AsList as EachSession>::Dual: List, 

impl<Choices: Any> Session for Choose<Choices> where
