Enum ShutdownReason 

pub enum ShutdownReason {
    UserRequested,
    RpcRequested,
    ReloadRequested,
    RequestedByRun,
    Fatal(String),
}

Why the service is shutting down.

Binaries map these to process exit codes:

• UserRequested / RequestedByRun / ReloadRequested → 0.
• RpcRequested → 0.
• Fatal(_) → non-zero.

Variants

UserRequested

SIGINT / SIGTERM / Ctrl-C.

RpcRequested

An admin RPC method (stop_node) requested shutdown.

ReloadRequested

A reload was requested; the binary should exit and re-spawn.

RequestedByRun

The node’s run method returned without any outside signal; the service treats that as a graceful exit.

Fatal(String)

An unrecoverable internal error. The string is human-readable.
