Struct SelectionSet 

pub struct SelectionSet { /* private fields */ }

Non-empty, sorted, non-overlapping selections plus the primary’s index.

Implementations

impl SelectionSet

pub fn single(sel: Selection) -> Self

pub fn caret(pos: ByteOffset) -> Self

pub fn new(ranges: Vec<Selection>, primary: usize) -> Self

Builds a normalized set. primary indexes into ranges as given. An empty ranges yields a caret at 0.

pub fn ranges(&self) -> &[Selection]

pub fn fits(&self, doc: &Document) -> bool

Whether this is a well-formed set for doc (non-empty, sorted, apart from each other as normalizing leaves them, every end on a character boundary of the text, a rectangle within its lines). A set read back from disk is checked with this before it is used.

pub fn primary(&self) -> &Selection

pub fn primary_index(&self) -> usize

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn rect(&self) -> Option<&Rectangle>

pub fn with_rect(self, rect: Option<Rectangle>) -> Self

pub fn map(&self, f: impl FnMut(&Selection) -> Selection) -> Self

Applies f to every selection, renormalizes and drops the rectangle.

pub fn validate(&self, doc: &Document) -> Result<(), String>

Checks the invariants; used by tests and debug assertions.
