Struct GoalCol 

pub struct GoalCol {
    pub goal_col: ColIdx,
}

A small helper for “preferred column” behavior (vim-like vertical motion).

When you move up/down, you usually want to keep the goal column even if a particular line is shorter. Store the goal separately from the actual column.

Typical usage:

• Update goal_col when moving left/right or after inserting text.
• When moving up/down, clamp to the target line length, but keep goal_col.

Fields

goal_col: ColIdx

Implementations

impl GoalCol

pub const fn new(goal_col: usize) -> Self

Trait Implementations

impl Clone for GoalCol

fn clone(&self) -> GoalCol

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GoalCol

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

Formats the value using the given formatter.

impl Default for GoalCol

fn default() -> GoalCol

Returns the “default value” for a type.

impl Hash for GoalCol

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 GoalCol

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