Struct SelRegion 

pub struct SelRegion {
    pub start: usize,
    pub end: usize,
    pub affinity: CursorAffinity,
    pub horiz: Option<ColPosition>,
}

Fields

start: usize

Region start offset

end: usize

Region end offset

affinity: CursorAffinity

The placement preference for rendering the cursor at wrapped lines

horiz: Option<ColPosition>

Horizontal rules for multiple selection

Implementations

impl SelRegion

pub fn new( start: usize, end: usize, affinity: CursorAffinity, horiz: Option<ColPosition>, ) -> SelRegion

Creates new SelRegion from start and end offset.

pub fn caret(offset: usize, affinity: CursorAffinity) -> SelRegion

Creates a caret SelRegion, i.e. start and end position are both set to offset value.

pub fn min(self) -> usize

Return the minimum value between region’s start and end position

Example:

let  region = SelRegion::new(1, 10, CursorAffinity::Backward, None);
assert_eq!(region.min(), region.start);
let  region = SelRegion::new(42, 1, CursorAffinity::Backward, None);
assert_eq!(region.min(), region.end);

pub fn max(self) -> usize

Return the maximum value between region’s start and end position.

Example:

let  region = SelRegion::new(1, 10, CursorAffinity::Backward, None);
assert_eq!(region.max(), region.end);
let  region = SelRegion::new(42, 1, CursorAffinity::Backward, None);
assert_eq!(region.max(), region.start);

pub fn is_caret(self) -> bool

A SelRegion is considered to be a caret when its start and end position are equal.

Example:

let  region = SelRegion::new(1, 1, CursorAffinity::Backward, None);
assert!(region.is_caret());

pub fn merge_with(self, other: SelRegion) -> SelRegion

Merge two SelRegion into a single one.

Example:

let  region = SelRegion::new(1, 2, CursorAffinity::Backward, None);
let  other = SelRegion::new(3, 4, CursorAffinity::Backward, None);
assert_eq!(region.merge_with(other), SelRegion::new(1, 4, CursorAffinity::Backward, None));

Trait Implementations

impl Clone for SelRegion

fn clone(&self) -> SelRegion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SelRegion

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SelRegion

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SelRegion

fn eq(&self, other: &SelRegion) -> 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 Serialize for SelRegion

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for SelRegion
