Enum CursorPosition

pub enum CursorPosition {
    InWord(usize),
    OnWordLeftEdge(usize),
    OnWordRightEdge(usize),
    InSpace(Option<usize>, Option<usize>),
}

Represents the position of the cursor relative to words in the buffer.

Variants

InWord(usize)

The cursor is in the word with the specified index.

OnWordLeftEdge(usize)

The cursor is on the left edge of the word with the specified index. For example: abc |hi, where | is the cursor.

OnWordRightEdge(usize)

The cursor is on the right edge of the word with the specified index. For example: abc| hi, where | is the cursor.

InSpace(Option<usize>, Option<usize>)

The cursor is not in contact with any word. Each Option<usize> specifies the index of the closest word to the left and right, respectively, or None if there is no word on that side.

Implementations

impl CursorPosition

pub fn get(cursor: usize, words: &[(usize, usize)]) -> CursorPosition

Trait Implementations

impl Clone for CursorPosition

fn clone(&self) -> CursorPosition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CursorPosition

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

Formats the value using the given formatter.

impl PartialEq for CursorPosition

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