Struct Cursor

pub struct Cursor {
    pub line: usize,
    pub index: usize,
    pub affinity: Affinity,
}

Current cursor location

Fields

line: usize

Index of [BufferLine] in [Buffer::lines]

index: usize

First-byte-index of glyph at cursor (will insert behind this glyph)

affinity: Affinity

Whether to associate the cursor with the run before it or the run after it if placed at the boundary between two runs

Implementations

impl Cursor

pub const fn new(line: usize, index: usize) -> Cursor

Create a new cursor

pub const fn new_with_affinity( line: usize, index: usize, affinity: Affinity, ) -> Cursor

Create a new cursor, specifying the affinity

Trait Implementations

impl Clone for Cursor

fn clone(&self) -> Cursor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cursor

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

Formats the value using the given formatter.

impl Default for Cursor

fn default() -> Cursor

Returns the “default value” for a type.

impl Ord for Cursor

fn cmp(&self, other: &Cursor) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Cursor

fn eq(&self, other: &Cursor) -> 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 PartialOrd for Cursor

fn partial_cmp(&self, other: &Cursor) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
