Struct FoldSet 

pub struct FoldSet { /* private fields */ }

The folded regions of one view, possibly nested.

Implementations

impl FoldSet

pub fn is_empty(&self) -> bool

pub fn headers(&self) -> impl Iterator<Item = usize> + '_

The folded header lines, in order.

pub fn is_folded(&self, header: usize) -> bool

pub fn hidden_range(&self, line: usize) -> Option<(usize, usize)>

The hidden line range (inclusive) holding line.

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

pub fn hidden_count(&self) -> usize

Hidden lines in total.

pub fn hidden_before(&self, line: usize) -> usize

Hidden lines before line.

pub fn visible_line(&self, index: usize, line_count: usize) -> usize

The line that is the index-th visible line (0-based), or the last visible one if there are fewer.

Trait Implementations

impl Clone for FoldSet

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FoldSet

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

Formats the value using the given formatter.

impl Default for FoldSet

fn default() -> Self

Returns the “default value” for a type.

impl Eq for FoldSet

impl PartialEq for FoldSet

fn eq(&self, other: &Self) -> bool
