Struct DocumentFolds 

pub struct DocumentFolds(pub Vec<Fold>);

Per-document fold list. Empty means “not yet computed for this buffer.” First-activation seeds from the active foldmethod; subsequent re-activations restore the user’s open / closed state. Universal across language majors – the foundational text-mode owns the data shape; per-language fold queries are a presentation-layer concern read through the syntax local.

Trait Implementations

impl BufferLocal for DocumentFolds

const NAME: &'static str = "text-mode.folds"

Public display name (:describe-buffer row label, debug logs). Convention: <owner-mode-name>.<key>, e.g. "file-tree.entries". Not a registry key — locals aren’t registered globally; the name is metadata for inspection.

const DOC: &'static str = "Per-document fold list. Empty until the activation hook \ seeds from the buffer's foldmethod; thereafter holds the \ user's open / closed state across buffer-switch \ round-trips."

Doc string. Shown in :describe-buffer when the user expands a local for detail.

const OWNER_MODE: &'static str = "text-mode"

Mode id that owns this local. Attribution metadata for :describe-buffer; the write-time check the design calls for (a ModeContext::set_local::<T> that rejects a non-owner) is not implemented, so nothing enforces it today (see the module docs).

fn describe(&self) -> String

Single-line summary of the local’s value for :describe-buffer’s tabular display. Implementations should be cheap (no heavy formatting); detailed inspection is via the mode’s own commands.

impl Clone for DocumentFolds

fn clone(&self) -> DocumentFolds

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DocumentFolds

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

Formats the value using the given formatter.

impl Default for DocumentFolds

fn default() -> DocumentFolds

Returns the “default value” for a type.
