Enum SessionHandlerKey 

pub enum SessionHandlerKey {
    Empty,
}

Typed key for session handler lookup.

This enum defines the purposes for which session handlers can be registered. Currently only Empty is supported for handling sessions without buffers.

Compile-Time Safety

Using typed keys instead of strings ensures:

• Typos are caught at compile time (SessionHandlerKey::Emtpy → error)
• Exhaustive matching in match statements
• Self-documenting API

Example

use reovim_driver_session::{SessionHandlerKey, SessionHandlerRegistry, EmptySessionHandler};
use std::sync::Arc;

let registry = SessionHandlerRegistry::new();
registry.register(SessionHandlerKey::Empty, Arc::new(ScratchBufferHandler::new()));

// Lookup with typed key
let handler = registry.get(&SessionHandlerKey::Empty);

Variants

Empty

Handler for empty sessions (no buffers).

When a session starts with no files specified, this handler determines what to do (e.g., create a scratch buffer, show welcome).

Trait Implementations

impl Clone for SessionHandlerKey

fn clone(&self) -> SessionHandlerKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionHandlerKey

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

Formats the value using the given formatter.

impl Hash for SessionHandlerKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SessionHandlerKey

fn eq(&self, other: &SessionHandlerKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ServiceKey for SessionHandlerKey

fn service_name() -> &'static str

Human-readable service name for error messages ONLY.
