Struct Terminal 

pub struct Terminal {
    pub action: ActionOption,
    pub channel: u16,
    pub mode: ModeOption,
    pub mode_state: Option<usize>,
    pub pop: bool,
}

Terminal instructions for the lexer logic.

Possible actions:

• skip => doesn’t return token, drops current string
• more => doesn’t return token, keeps current string for next rule
• push(n) => pushes mode and switches to mode n
• pop => pops next mode from the stack
• channel # => defines output channel

By default, push, pop, channel or no specified action outputs a token (token = Some(..)). If a skip or more action is specified, no token is returned (token = None).

Fields

action: ActionOption

channel: u16

mode: ModeOption

mode_state: Option<usize>

pop: bool

Trait Implementations

impl Add for Terminal

type Output = Terminal

The resulting type after applying the + operator.

fn add(self, rhs: Terminal) -> <Terminal as Add>::Output

Performs the + operation.

impl Clone for Terminal

fn clone(&self) -> Terminal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Terminal

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

Formats the value using the given formatter.

impl Default for Terminal

fn default() -> Terminal

Returns the “default value” for a type.

impl Display for Terminal

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

Formats the value using the given formatter.

impl Ord for Terminal

fn cmp(&self, other: &Terminal) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Terminal

fn eq(&self, other: &Terminal) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Terminal

fn partial_cmp(&self, other: &Terminal) -> Option<Ordering>

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

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

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

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
