keetanetwork-client 0.2.0

Async REST client for transmitting vote staples to a KeetaNet node
//! Conditional `Send`/`Sync` bounds for the client's async traits.
//!
//! Some native targets require `Send + Sync` so a multi-threaded
//! executor (e.g. `tokio`) can drive them. On wasm, futures are
//! single-threaded and browser values are `!Send`, so the bounds relax to
//! nothing, letting a fetch-based backend implement the same traits.
