Struct tvix_eval::chunk::SourceSpan

struct SourceSpan {
    span: Span,
    start: usize,
}

Represents a source location from which one or more operations were compiled.

The span itself is an index into a codemap::CodeMap, and the structure tracks the number of operations that were yielded from the same span.

At error reporting time, it becomes possible to either just fetch the textual representation of that span from the codemap, or to even re-parse the AST using rnix to create more semantically interesting errors.

Fields

span: Span

Span into the codemap::CodeMap.

start: usize

Index of the first operation covered by this span.

Trait Implementations

impl Clone for SourceSpan

fn clone(&self) -> SourceSpan

Returns a copy 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.
