Struct CharRange 

pub struct CharRange {
    pub start: CharIdx,
    pub end: CharIdx,
}

A half-open character range: [start, end).

Invariant expected by users:

• start <= end

When working with ropey, indices are in chars (not bytes).

Fields

start: CharIdx

end: CharIdx

Implementations

impl CharRange

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

pub const fn is_empty(self) -> bool

pub const fn len(self) -> usize

pub const fn normalized(self) -> Self

Normalizes so that start <= end.

pub fn clamp_to_len(self, max_len: usize) -> Self

Clamp the range to [0, max].

Trait Implementations

impl Clone for CharRange

fn clone(&self) -> CharRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CharRange

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

Formats the value using the given formatter.

impl Default for CharRange

fn default() -> CharRange

Returns the “default value” for a type.

impl Hash for CharRange

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CharRange

fn eq(&self, other: &CharRange) -> 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.
