Struct BootstrapState 

pub struct BootstrapState {
    pub mode_stack: ModeStack,
    pub windows: WindowLayout,
    pub pending_keys: KeySequence,
    pub extensions: ExtensionMap,
}

Bootstrap state for creating a new session with initial per-client data.

This struct provides the initial per-client state needed when initializing a session or adding the first client. It contains fields that will become part of EditingState in the server layer.

Usage

// Create session with bootstrap state for tests
let (session, bootstrap) = Session::bootstrap(ClientId::new(1), home_mode);

// Use bootstrap fields for per-client state
let mode_stack = bootstrap.mode_stack;
let windows = bootstrap.windows;

Architecture (#488)

This type exists to provide a clean separation between:

• Session: Shared infrastructure only (SessionShared)
• BootstrapState: Initial per-client state (mode, windows, extensions)

At runtime, per-client state lives in EditingState in the server layer.

Fields

mode_stack: ModeStack

Initial mode stack with home mode at the bottom.

windows: WindowLayout

Initial window layout (empty by default).

pending_keys: KeySequence

Initial pending keys (empty by default).

extensions: ExtensionMap

Initial extensions map (empty by default).

Implementations

impl BootstrapState

pub fn new(home_mode: ModeId) -> Self

Create bootstrap state with the given home mode.

The home mode becomes the bottom of the mode stack. Windows, pending keys, and extensions start empty.

pub fn with_buffer(home_mode: ModeId, buffer_id: BufferId) -> Self

Create bootstrap state with a window for the given buffer.

This is useful when the session already has an active buffer and the new client should have a window showing that buffer.

Trait Implementations

impl Debug for BootstrapState

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

Formats the value using the given formatter.
