Struct tvix_eval::chunk::SourceSpan

source ·
struct SourceSpan {
    span: Span,
    start: usize,
}
Expand description

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.

impl PartialEq for SourceSpan

source§

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