Enum hime_sdk::grammars::TerminalRef

pub enum TerminalRef {
    Dummy,
    Epsilon,
    Dollar,
    NullTerminal,
    Terminal(usize),
}

Represents a reference to a terminal-like

Variants

Dummy

Represents a fake terminal, used as a marker by LR-related algorithms

Epsilon

Represents the epsilon symbol in a grammar, i.e. a terminal with an empty value

Dollar

Represents the dollar symbol in a grammar, i.e. the marker of end of input

NullTerminal

Represents the absence of terminal, used as a marker by LR-related algorithms

Terminal(usize)

A terminal in a grammar

Implementations

impl TerminalRef

pub fn sid(self) -> usize

Gets the symbol id for the terminal

pub fn priority(self) -> usize

Gets the terminal priority

Trait Implementations

impl Clone for TerminalRef

fn clone(&self) -> TerminalRef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TerminalRef

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

Formats the value using the given formatter.

impl From<FinalItem> for TerminalRef

fn from(final_item: FinalItem) -> Self

Converts to this type from the input type.

impl From<TerminalRef> for SymbolRef

fn from(terminal: TerminalRef) -> Self

Converts to this type from the input type.

impl Hash for TerminalRef

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TerminalRef

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<TerminalRef> for TerminalRef

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<TerminalRef> for TerminalRef

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

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

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

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

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

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

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

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

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

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