Function resize [src]

Resizes the connection pool. If the new size is smaller than the current size, then idle connections will be closed until the pool is the new size. Threadsafe.

Prototype

pub fn resize(pool: *ConnectionPool, allocator: Allocator, new_size: usize) void

Parameters

pool: *ConnectionPoolallocator: Allocatornew_size: usize

Source

  pub fn resize(pool: *ConnectionPool, allocator: Allocator, new_size: usize) void {
    pool.mutex.lock();
    defer pool.mutex.unlock();

    const next = pool.free.first;
    _ = next;
    while (pool.free_len > new_size) {
        const popped = pool.free.popFirst() orelse unreachable;
        pool.free_len -= 1;

        popped.data.close(allocator);
        allocator.destroy(popped);
    }

    pool.free_size = new_size;
}
