pub struct Span { /* fields omitted */ }

A span in the JavaScript source code.

Stores a start position and an end position.

Implementations

impl Span

pub fn new(start: Position, end: Position) -> Self

Creates a new Span.

pub fn start(self) -> Position

Gets the starting position of the span.

pub fn end(self) -> Position

Gets the final position of the span.

pub fn contains<S>(self, other: S) -> bool where
    S: Into<Self>, 

Checks if this span inclusively contains another span or position.
