Struct NvimSnapshot 

pub struct NvimSnapshot {
    pub lines: Vec<String>,
    pub cursor: (usize, usize),
    pub mode: EditorMode,
    pub cmdline: Option<String>,
    pub dirty: bool,
    pub content_gen: u64,
    pub visual_selection: Option<((usize, usize), (usize, usize))>,
}

Cached state from a running nvim --embed process.

Written by async refresh tasks; read synchronously by the render path.

Fields

lines: Vec<String>

Buffer lines (0-indexed).

cursor: (usize, usize)

Cursor position (row, col), 0-indexed.

mode: EditorMode

cmdline: Option<String>

Set when mode is Command — the full command line including the type prefix (e.g., ":set nu" or "/pattern"). None in all other modes.

dirty: bool

true after every keystroke, cleared by mark_saved().

content_gen: u64

Monotonically increasing; incremented every time lines actually changes. Used by view.update() so the parse cache is rebuilt from fresh content, not from whatever lines happened to be in the snapshot when the key was pressed.

visual_selection: Option<((usize, usize), (usize, usize))>

Active visual selection in logical (row, char-col) coordinates, 0-indexed. None when not in a visual mode. For VisualLine the end col is usize::MAX.

Implementations

impl NvimSnapshot

pub fn footer_label(&self) -> String

The string to display in the footer mode indicator.

In command mode, shows the live command line with a block cursor appended. In all other modes, shows the mode label (e.g., "NORMAL").

Trait Implementations

impl Clone for NvimSnapshot

fn clone(&self) -> NvimSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NvimSnapshot

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

Formats the value using the given formatter.

impl Default for NvimSnapshot

fn default() -> Self

Returns the “default value” for a type.
