Struct `Span`

struct Span { ... }

Span represents the position information of a single AST item.

All span positions are absolute byte offsets that can be used on the original regular expression that was parsed.

Fields

start: Position: The start byte offset.
end: Position: The end byte offset.

Implementations

`impl Span`

fn new(start: Position, end: Position) -> Span: Create a new span with the given positions.
fn splat(pos: Position) -> Span: Create a new span using the given position as the start and end.
fn with_start(self: Self, pos: Position) -> Span: Create a new span by replacing the starting the position with the one given.
fn with_end(self: Self, pos: Position) -> Span: Create a new span by replacing the ending the position with the one given.
fn is_one_line(self: &Self) -> bool: Returns true if and only if this span occurs on a single line.
fn is_empty(self: &Self) -> bool: Returns true if and only if this span is empty. That is, it points to a single position in the concrete syntax of a regular expression.
