Struct regex_syntax::ast::Span

source ·
pub struct Span {
    pub start: Position,
    pub end: Position,
}
Expand description

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§

source§

impl Span

source

pub fn new(start: Position, end: Position) -> Span

Create a new span with the given positions.

source

pub fn splat(pos: Position) -> Span

Create a new span using the given position as the start and end.

source

pub fn with_start(self, pos: Position) -> Span

Create a new span by replacing the starting the position with the one given.

source

pub fn with_end(self, pos: Position) -> Span

Create a new span by replacing the ending the position with the one given.

source

pub fn is_one_line(&self) -> bool

Returns true if and only if this span occurs on a single line.

source

pub fn is_empty(&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.
