Struct NoopFoldProvider 

pub struct NoopFoldProvider;

No-op FoldProvider for hosts that don’t expose folds. Every row is visible; is_row_hidden always returns false.

Trait Implementations

impl Clone for NoopFoldProvider

fn clone(&self) -> NoopFoldProvider

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NoopFoldProvider

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

Formats the value using the given formatter.

impl Default for NoopFoldProvider

fn default() -> NoopFoldProvider

Returns the “default value” for a type.

impl FoldProvider for NoopFoldProvider

fn next_visible_row(&self, row: usize, row_count: usize) -> Option<usize>

First visible row strictly after row, skipping hidden rows. None past the end of the buffer.

fn prev_visible_row(&self, row: usize) -> Option<usize>

First visible row strictly before row. None past the top.

fn is_row_hidden(&self, _row: usize) -> bool

Is row currently hidden by a closed fold?

fn fold_at_row(&self, _row: usize) -> Option<(usize, usize, bool)>

Range (start_row, end_row, closed) of the fold containing row, if any. Lets za / zo / zc find their target without iterating the full fold list.

fn apply(&mut self, op: FoldOp)

Apply a FoldOp to the underlying fold storage. Read-only providers (e.g. crate::buffer_impl::BufferFoldProvider which holds a &Buffer) and providers that don’t track folds (e.g. NoopFoldProvider) implement this as a no-op.

fn invalidate_range(&mut self, start_row: usize, end_row: usize)

Drop every fold whose range overlaps [start_row, end_row]. Edit pipelines call this after a user edit so vim’s “edits inside a fold open it” behaviour fires. Default impl forwards to FoldProvider::apply with a FoldOp::Invalidate.
