Struct AsyncBridge 

pub struct AsyncBridge { /* private fields */ }

Bridge between async Tokio runtime and sync main loop

Design:

• Lightweight, cloneable sender that can be passed to async tasks
• Non-blocking receiver checked each frame in main loop
• No locks needed in main loop (channel handles synchronization)

Implementations

impl AsyncBridge

pub fn new() -> Self

Create a new async bridge with an unbounded channel

Unbounded is appropriate here because:

1. Main loop processes messages every 16ms (60fps)
2. LSP messages are infrequent (< 100/sec typically)
3. Memory usage is bounded by message rate × frame time

pub fn sender(&self) -> Sender<AsyncMessage>

Get a cloneable sender for async tasks

This sender can be:

• Cloned freely (cheap Arc internally)
• Sent to async tasks
• Stored in LspClient instances

pub fn try_recv_all(&self) -> Vec<AsyncMessage>

Try to receive pending messages (non-blocking)

Called each frame in the main loop to process async messages. Returns all pending messages without blocking.

pub fn has_messages(&self) -> bool

Check if there are pending messages (non-blocking)

Trait Implementations

impl Clone for AsyncBridge

fn clone(&self) -> AsyncBridge

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for AsyncBridge

fn default() -> Self

Returns the “default value” for a type.
