Struct SpanMap 

pub struct SpanMap { /* private fields */ }

Map from dotted field path to source span. Built by the saphyr parser; consumed by diagnose_resource_with_spans (Task 4) to attach positions to diagnostics.

Implementations

impl SpanMap

pub fn new(file: PathBuf) -> Self

Create a new SpanMap associated with the given source file path.

pub fn insert( &mut self, path: impl Into<String>, line: u32, col: u32, end_line: u32, end_col: u32, )

Insert a span for the given dotted path.

Lines and columns are 1-indexed; end_col is exclusive.

pub fn lookup(&self, path: &str) -> Option<Span>

Look up the span for the given dotted path, returning a Span if found.

pub fn is_empty(&self) -> bool

Return true if no spans have been inserted.

pub fn len(&self) -> usize

Return the number of spans in this map.
