Implementations

impl BackendState

pub fn is_textarea(&self) -> bool

Whether the textarea backend is active — the named form of the structural guard, for sites that only need the yes/no.

pub fn as_textarea(&self) -> Option<&TextArea<'static>>

The textarea, when it is the active backend. Textarea-only features (autocomplete, smart edits, mouse selection) guard on this.

pub fn as_textarea_mut(&mut self) -> Option<&mut TextArea<'static>>

pub fn as_nvim(&self) -> Option<&NvimBackend>

The nvim backend, when it is the active one.

pub fn text(&self) -> String

The whole buffer as one string, whichever backend holds it.

pub fn cursor(&self) -> (usize, usize)

The cursor’s (row, col), cheap on both backends — no line cloning. The nvim row is clamped to the mirrored line count (the mirror can lag the real cursor for a frame), matching the snapshot path.

pub fn recover_from_dead_nvim(&mut self) -> bool

If the nvim backend’s process has died, replace it with a textarea holding the last mirrored buffer, and report that it happened so the host can re-arm textarea-only features.

pub fn from_settings( editor_backend: &EditorBackendSetting, nvim_path: Option<&PathBuf>, ) -> Self
