Struct codemap::Span

pub struct Span { /* fields omitted */ }

A range of text within a CodeMap.

Methods

impl Span

pub fn subspan(&self, begin: u64, end: u64) -> Span

Makes a span from offsets relative to the start of this span.

Panics

• If end < begin
• If end is beyond the length of the span

pub fn contains(&self, other: Span) -> bool

Checks if a span is contained within this span.

pub fn low(&self) -> Pos

The position in the codemap representing the first byte of the span.

pub fn high(&self) -> Pos

The position after the last byte of the span.

pub fn len(&self) -> u64

The length in bytes of the text of the span

pub fn merge(&self, other: Span) -> Span

Create a span that encloses both self and other.
