Struct NoiseCryptoProvider 

pub struct NoiseCryptoProvider {
    crypto_state_guard: Mutex<()>,
}

A CryptoProvider that encrypts IPC traffic using the Noise protocol.

Fields

crypto_state_guard: Mutex<()>

Serializes access to the persisted transport state, so that two concurrent sends cannot read the same copy and reuse a nonce.

Held per provider, and so per IpcClientImpl, rather than per process: the state it protects belongs to one client’s session repository, and a process-wide lock would let one client’s handshake — which can wait HANDSHAKE_TIMEOUT_SECS for a reply — stall every other client’s traffic.

Implementations

impl NoiseCryptoProvider

pub fn new() -> Self

Creates a provider with no sessions established.
