Struct RpcPool 

pub struct RpcPool { /* private fields */ }

A minimal connection pool.

Implementations

impl RpcPool

pub fn new(config: RpcPoolConfig) -> Self

Build a new pool. Does NOT open any connections eagerly; the first acquire() call dials the first connection.

pub async fn acquire(&self) -> Result<PooledClient, RpcClientError>

Acquire a client from the pool. Blocks (asynchronously) when the pool is at capacity until a slot frees. The returned PooledClient returns the client to the pool on Drop.

pub fn idle_count(&self) -> usize

Number of idle clients currently sitting in the pool. Useful for diagnostics and testing — production code should not branch on this.
