[−][src]Struct oak_runtime::file_map_stream::Span
Spans represent a region of code, used for error reporting. Positions in spans are absolute positions from the beginning of the codemap, not positions relative to FileMaps. Methods on the CodeMap can be used to relate spans back to the original source. You must be careful if the span crosses more than one file - you will not be able to use many of the functions on spans in codemap and you cannot assume that the length of the span = hi - lo; there may be space in the BytePos range between files.
Fields
lo: BytePos
hi: BytePos
expn_id: ExpnId
Information about where the macro came from, if this piece of code was created by a macro expansion.
Implementations
impl Span
[src]
pub fn end_point(self) -> Span
[src]
Returns a new span representing just the end-point of this span
pub fn substitute_dummy(self, other: Span) -> Span
[src]
Returns self
if self
is not the dummy span, and other
otherwise.
pub fn contains(self, other: Span) -> bool
[src]
pub fn source_equal(&self, other: &Span) -> bool
[src]
Return true if the spans are equal with regards to the source text.
Use this instead of ==
when either span could be generated code,
and you only care that they point to the same bytes of source text.
pub fn trim_start(self, other: Span) -> Option<Span>
[src]
Returns Some(span)
, where the start is trimmed by the end of other
