Struct nlprule::types::Span

pub struct Span { /* fields omitted */ }

A span in a text determined by start (inclusive) and end (exclusive) position. The start must always be greater than or equal to the end.

Implementations

impl Span

pub fn from_positions(start: Position, end: Position) -> Self

Creates a new span from start and end Position.

Panics

• If the end is smaller than the start.

pub fn new(byte: Range<usize>, char: Range<usize>) -> Self

Creates a new span from a byte and char range.

pub fn start(&self) -> Position

Gets the start position.

pub fn end(&self) -> Position

Gets the end position.

pub fn byte(&self) -> &Range<usize>

Gets the byte range.

pub fn char(&self) -> &Range<usize>

Gets the char range.

pub fn is_empty(&self) -> bool

Checks whether this span is empty.y

pub fn len(&self) -> Position

Gets the length of this span.

pub fn set_start(&mut self, start: Position)

Sets the start position.

pub fn set_end(&mut self, end: Position)

Sets the end position.

pub fn rshift(self, position: Position) -> Self

Shift the span right by the specified amount.

pub fn lshift(self, position: Position) -> Self

Shift the span left by the specified amount. Clips at zero if the resulting span would have a negative component.

Trait Implementations
