Expand description
A Span
records what portion of the user’s input something (e.g. a lexeme or production)
references (i.e. the Span
doesn’t hold a reference / copy of the actual input).
Create a new span starting at byte start
and ending at byte end
.
If end
is less than start
.
Byte offset of the start of the span.
Byte offset of the end of the span.
Length in bytes of the span.
Returns true
if this Span
covers 0 bytes, or false
otherwise.
