Struct ListCursor 

pub struct ListCursor {
    pub position: usize,
    pub text_row: usize,
}

A position within a list.

Fields

position: usize

The position of the selected item within the list.

text_row: usize

A row within the Text representation of the selected ListItem.

Implementations

impl ListCursor

pub fn new(position: usize, text_row: usize) -> Self

Create a new cursor for a list.

Trait Implementations

impl Clone for ListCursor

fn clone(&self) -> ListCursor

Returns a duplicate of the value.

Performs copy-assignment from source.

impl<T, I> CursorMovements<ListCursor> for ListState<T, I>

where T: ListItem<I>, I: ApplicationInfo,

Calculate the position of the first word on the line of the provided cursor.

fn movement( &self, pos: &ListCursor, movement: &MoveType, count: &Count, ctx: &CursorMovementsContext<'_, ListCursor>, ) -> Option<ListCursor>

Calculate the position of the cursor after performing a movement.

fn range_of_movement( &self, pos: &ListCursor, movement: &MoveType, count: &Count, ctx: &CursorMovementsContext<'_, ListCursor>, ) -> Option<EditRange<ListCursor>>

Calculate a cursor range from the given cursor to the location after performing the given movement.

fn range( &self, pos: &ListCursor, range: &RangeType, _: bool, count: &Count, ctx: &CursorMovementsContext<'_, ListCursor>, ) -> Option<EditRange<ListCursor>>

Calculate a cursor range based on a given cursor position and a RangeType.

impl<T, I> CursorSearch<ListCursor> for ListState<T, I>

where T: ListItem<I>, I: ApplicationInfo,

fn find_char( &self, _: &ListCursor, _: bool, _: MoveDir1D, _: bool, _: char, _: usize, ) -> Option<ListCursor>

Search for a specific character.

fn find_matches( &self, _: &ListCursor, _: &ListCursor, _: &Regex, ) -> Vec<EditRange<ListCursor>>

Find matches for a regular expression within a range.

fn find_regex( &self, pos: &ListCursor, dir: MoveDir1D, needle: &Regex, count: usize, ) -> Option<EditRange<ListCursor>>

Search for a regular expression.

impl Debug for ListCursor

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

Formats the value using the given formatter.

impl Default for ListCursor

fn default() -> ListCursor

Returns the “default value” for a type.

impl From<usize> for ListCursor

fn from(position: usize) -> Self

Converts to this type from the input type.

impl Ord for ListCursor

fn cmp(&self, other: &Self) -> 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 ListCursor

fn eq(&self, other: &ListCursor) -> 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 ListCursor

fn partial_cmp(&self, other: &Self) -> 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.
