Struct SourceSpan 

pub struct SourceSpan { /* private fields */ }

Represents a span of source code.

Implementations

impl SourceSpan

pub fn new( start: SourceLocation, end: SourceLocation, ) -> Result<Self, SpanError>

Constructs a new span from two locations.

Examples

use whitaker_common::span::{SourceLocation, SourceSpan};

let span = SourceSpan::new(SourceLocation::new(1, 0), SourceLocation::new(3, 2)).expect("valid span for example");
assert_eq!(span.start().line(), 1);

pub const fn start(self) -> SourceLocation

Returns the start location.

pub const fn end(self) -> SourceLocation

Returns the end location.

Trait Implementations

impl Clone for SourceSpan

fn clone(&self) -> SourceSpan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceSpan

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

Formats the value using the given formatter.

impl PartialEq for SourceSpan

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