Enum RpcErrorCode 

#[non_exhaustive]
pub enum RpcErrorCode {
    NotFound,
    InvalidConfig,
    SpawnFailed,
    ProtocolMismatch,
    Internal,
    DeadlineExceeded,
    Unsupported,
    Unrecognized,
}

Machine-readable RPC error codes

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotFound

Selector matched nothing

InvalidConfig

Config failed validation daemon-side

SpawnFailed

Spawn failed (exec error, permissions)

ProtocolMismatch

Handshake protocol version mismatch

Internal

Unexpected daemon-side failure

DeadlineExceeded

The request’s deadline expired before the daemon finished it

Unsupported

The peer asked for something this build does not implement.

Distinct from NotFound, which means a selector matched nothing. This means the verb itself is unknown here, and the remedy is a newer shepherd rather than a different selector.

Unrecognized

A code this build has not been taught.

Only ever produced by decoding: an unrecognized string falls through to this variant via #[serde(other)] instead of failing the whole frame. Nothing constructs one to send, which is a call-site invariant rather than a type-level one: #[serde(other)] governs decoding only, so serializing this would emit "unrecognized".

Implementations

impl RpcErrorCode

pub const ALL: [Self; 7]

Every variant, for code that needs to iterate them all.

#[non_exhaustive] forces a _ arm on any match written outside this crate, which would swallow a variant added here and never updated there (crates/shep-cli/src/exit.rs maps every code to an exit status).
