Struct Expression 

pub struct Expression<'source> {
    pub first_token: Option<Token<'source>>,
    pub last_token: Option<Token<'source>>,
    pub diagnostics: Diagnostics<'source>,
    pub contents: [Node<'source>],
}

This type should not contain an incomplete expression so long as there are no error diagnostics.

Fields

first_token: Option<Token<'source>>

last_token: Option<Token<'source>>

diagnostics: Diagnostics<'source>

contents: [Node<'source>]

Implementations

impl<'source> Expression<'source>

pub fn build<G>( first_token: Option<Token<'source>>, last_token: Option<Token<'source>>, diagnostics: Diagnostics<'source>, contents: G, ) -> Box<Self>

where G: IntoIterator<Item = Node<'source>>, <G as IntoIterator>::IntoIter: ExactSizeIterator,

Creates an instance of Box<Expression>.

pub fn build_from_slice( first_token: Option<Token<'source>>, last_token: Option<Token<'source>>, diagnostics: Diagnostics<'source>, contents: &[Node<'source>], ) -> Box<Self>

where Node<'source>: Copy,

Creates an instance of Box<Expression>.

pub fn destructure( this: Box<Self>, ) -> (Option<Token<'source>>, Option<Token<'source>>, Diagnostics<'source>, ExpressionIter<'source>)

Destructures an instance of Box<Expression>, returning the tail slice as an iterator.

impl<'source> Expression<'source>

pub fn new(lexer: &mut Peekable<Lexer<'source>>) -> Option<Box<Self>>

Parse an expression until an unexpected token is upcoming (via peek).

Trait Implementations

impl<'source> Debug for Expression<'source>

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

Formats the value using the given formatter.

impl<'source> PartialEq for Expression<'source>

fn eq(&self, other: &Expression<'source>) -> 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.
