weir-client 4.0.1

//! Push records to a running weir daemon across both durability tiers.
//!
//! Usage:
//!   cargo run -p weir-client --example push_simple -- [--socket <path>] [--count <n>]
//!
//! Defaults: socket = /run/weir/weir.sock, count = 5
//!
//! Each push prints whether it was acked and how long it took.
