Struct Range

pub struct Range {
    pub start: usize,
    pub end: usize,
}

Positional information about a start and end point in the text.

Fields

start: usize

Start position of the node in the text.

end: usize

End position of the node in the text.

Implementations

impl Range

pub fn new(start: usize, end: usize) -> Self

pub fn from_byte_index(pos: usize) -> Self

Trait Implementations

impl Clone for Range

fn clone(&self) -> Range

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Range

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Range

fn eq(&self, other: &Range) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Ranged for Range

fn range(&self) -> Range

Gets the range.

fn start(&self) -> usize

Gets the byte index of the first character in the text.

fn end(&self) -> usize

Gets the byte index after the last character in the text.

fn text<'a>(&self, text: &'a str) -> &'a str

Gets the text from the provided string.

fn width(&self) -> usize

Gets the end byte index minus the start byte index of the range.

impl Copy for Range

impl StructuralPartialEq for Range
