Struct Span 

pub struct Span { /* private fields */ }

A range of text within a CodeMap.

Implementations

impl Span

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

Checks if a span is contained within this span.

pub const fn low(&self) -> Pos

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

pub const fn high(&self) -> Pos

The position after the last byte of the span.

pub const fn len(&self) -> u64

The length in bytes of the text of the span

pub const fn is_empty(&self) -> bool

Checks whether the span is empty

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

Create a span that encloses both self and other.

Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Span

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

Formats the value using the given formatter.

impl Hash for Span

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 PartialEq for Span

fn eq(&self, other: &Span) -> 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.
