Struct Range 

pub struct Range {
    pub start: Position,
    pub end: Position,
    pub is_linewise: bool,
}

Text range for operator execution.

Represents a contiguous range of text in a buffer. Used by operators to know which text to act on.

The is_linewise flag indicates whether the range should be treated as spanning complete lines (e.g., yj, dd) or character positions (e.g., yw, d$).

Fields

start: Position

Start position (inclusive).

end: Position

End position (exclusive).

is_linewise: bool

Whether this range represents linewise selection.

Linewise ranges affect paste behavior:

• true: Paste inserts on new lines (above/below)
• false: Paste inserts inline at cursor

Implementations

impl Range

pub const fn new(start: Position, end: Position) -> Self

Create a new characterwise range (default).

pub const fn linewise(start: Position, end: Position) -> Self

Create a new linewise range.

pub const fn from_position(pos: Position) -> Self

Create a range from a single position (zero-width, characterwise).

pub const fn to_linewise(self) -> Self

Convert this range to linewise.

pub const fn is_empty(&self) -> bool

Check if the range is empty.

pub const fn is_single_line(&self) -> bool

Check if this is a single-line range.

pub const fn line_count(&self) -> usize

Get the number of lines spanned.

pub fn normalized(self) -> Self

Normalize the range so start <= end.

Trait Implementations

impl Clone for Range

fn clone(&self) -> Range

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Range

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

Formats the value using the given formatter.

impl PartialEq for Range

fn eq(&self, other: &Range) -> 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 Copy for Range

impl Eq for Range

impl StructuralPartialEq for Range
