Struct FoldState 

pub struct FoldState {
    pub ranges: Vec<FoldRange>,
    pub closed: HashSet<usize>,
    /* private fields */
}

Fields

ranges: Vec<FoldRange>

All detected fold ranges (start → end).

closed: HashSet<usize>

Start lines of currently closed folds.

Implementations

impl FoldState

pub fn new() -> Self

pub fn clear(&mut self)

pub fn rebuild(&mut self, lines: &[String], tab_width: usize)

Rebuild indent folds from buffer lines.

pub fn fold_at(&self, row: usize) -> Option<FoldRange>

pub fn is_closed(&self, start: usize) -> bool

pub fn is_hidden(&self, row: usize) -> bool

True if row is hidden inside a closed fold (not the header line).

pub fn toggle(&mut self, row: usize) -> Option<&'static str>

pub fn close_at(&mut self, row: usize) -> bool

pub fn open_at(&mut self, row: usize) -> bool

pub fn close_all(&mut self)

pub fn open_all(&mut self)

pub fn closed_count(&self, start: usize) -> usize

Lines hidden under a closed fold starting at start.
