Enum Adjustment 

#[non_exhaustive]
#[repr(u32)]
pub enum Adjustment {
    Left = 0,
    Right = 1,
    Up = 2,
    Down = 3,
    Home = 4,
    End = 5,
    PageUp = 6,
    PageDown = 7,
    BeginningOfLine = 8,
    EndOfLine = 9,
}

Operation used to adjust a selection endpoint.

Adjustment mutates the selection’s logical end endpoint, not whichever endpoint is visually bottom/right. This preserves keyboard and drag behavior for both forward and reversed selections.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Left = 0

Move left to the previous non-empty cell, wrapping upward.

Right = 1

Move right to the next non-empty cell, wrapping downward.

Up = 2

Move up one row at the current column, or to the beginning of the line if already at the top.

Down = 3

Move down to the next non-blank row at the current column, or to the end of the line if none exists.

Home = 4

Move to the top-left cell of the screen.

End = 5

Move to the right edge of the last non-blank row on the screen.

PageUp = 6

Move up by one terminal page height, or to home if that would move past the top.

PageDown = 7

Move down by one terminal page height, or to end if that would move past the bottom.

BeginningOfLine = 8

Move to the left edge of the current line.

EndOfLine = 9

Move to the right edge of the current line.

Trait Implementations

impl Clone for Adjustment

fn clone(&self) -> Adjustment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Adjustment

impl Debug for Adjustment

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

Formats the value using the given formatter.

impl Eq for Adjustment

impl From<Adjustment> for u32

fn from(v: Adjustment) -> Self

Converts to this type from the input type.

impl PartialEq for Adjustment

fn eq(&self, other: &Adjustment) -> 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 StructuralPartialEq for Adjustment

impl TryFrom<u32> for Adjustment

type Error = u32

The type returned in the event of a conversion error.

fn try_from(v: u32) -> Result<Self, u32>

Performs the conversion.
