Struct ucglib::ast::Token

pub struct Token {
    pub typ: TokenType,
    pub fragment: String,
    pub pos: Position,
}

Defines a Token representing a building block of UCG syntax.

Token's are passed to the parser stage to be parsed into an AST.

Fields

typ: TokenType

fragment: String

pos: Position

Methods

impl Token

pub fn new<S: Into<String>, P: Into<Position>>(
    f: S,
    typ: TokenType,
    p: P
) -> Self

Constructs a new Token with a type and line and column information.

pub fn new_with_pos<S: Into<String>>(
    f: S,
    typ: TokenType,
    pos: Position
) -> Self

Trait Implementations

impl PartialOrd<Token> for Token

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

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

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

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

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

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

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

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

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

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

impl<'a> From<&'a Token> for PositionedItem<String>

fn from(t: &'a Token) -> PositionedItem<String>

Performs the conversion.

impl PartialEq<Token> for Token

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

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

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

This method tests for !=.

impl Clone for Token

fn clone(&self) -> Token

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Ord for Token

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl Hash for Token

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, 

Feeds a slice of this type into the given [Hasher].

impl Borrow<str> for Token

fn borrow(&self) -> &str
