Struct swc_common::Span[][src]

#[repr(C)]
pub struct Span { pub lo: BytePos, pub hi: BytePos, pub ctxt: SyntaxContext, }
Expand description

Spans represent a region of code, used for error reporting. Positions in spans are absolute positions from the beginning of the source_map, not positions relative to SourceFiles. Methods on the SourceMap 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 source_map and you cannot assume that the length of the span = hi - lo; there may be space in the BytePos range between files.

Fields

lo: BytePoshi: BytePosctxt: SyntaxContext

Information about where the macro came from, if this piece of code was created by a macro expansion.

Implementations

Returns true if this is a dummy span with any hygienic context.

Returns a new span representing an empty span at the beginning of this span

Returns a new span representing an empty span at the end of this span

Returns self if self is not the dummy span, and other otherwise.

Return true if self fully encloses other.

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.

Returns Some(span), where the start is trimmed by the end of other

Return a Span that would enclose both self and end.

Return a Span between the end of self to the beginning of end.

Return a Span between the beginning of self to the beginning of end.

Returns true if self is marked with mark.

Panics if mark is not a valid mark.
