Struct Tail

#[repr(C)]
pub struct Tail<Q, S> {
    pub direction: Direction,
    pub state: State<Q>,
    pub symbol: S,
}

The Tail is a 3-tuple containing the direction, state, and symbol that an actor is instructed to execute whenever it assumes the head configuration assigned to the tail.

Fields

direction: Direction

state: State<Q>

symbol: S

Implementations

consumes the tail and returns the direction, state, and symbol as a 3-tuple

pub const fn direction(&self) -> Direction

returns the direction the head is instructed to move

pub const fn state(&self) -> &State<Q>

returns the next state with an immutable reference to the inner value

returns the next state with a mutable reference to the inner value

pub const fn symbol(&self) -> &S

returns the symbol the head is instructed to write

pub const fn symbol_mut(&mut self) -> &mut S

updates the current state and returns a mutable reference to the tail

pub fn set_symbol(&mut self, symbol: S) -> &mut Self

pub fn with_direction(self, direction: Direction) -> Self

Configures the tail with a new direction

pub fn with_state(self, State: State<Q>) -> Self

pub fn as_head(&self) -> Head<&Q, &S>

converts a Tail reference into an owned head.

pub fn into_head(self) -> Head<Q, S>

consumes the current tail to convert it into a head

pub const fn view(&self) -> Tail<&Q, &S>

returns an instance of the head where each element within the created instance is a mutable reference

pub fn view_mut(&mut self) -> Tail<&mut Q, &mut S>

returns a new Tail containing mutabl references to the state and symbol

pub fn to_ref(&self) -> Tail<&Q, &S>

👎Deprecated since 0.0.7: use view instead, as it is more idiomatic and clearer.

pub fn to_mut(&mut self) -> Tail<&mut Q, &mut S>

👎Deprecated since 0.0.7: use view_mut instead, as it is more idiomatic and clearer.
