Module request 

RPC frames: requests, responses, envelopes, and structured errors

Structs

ActionReply

One matched sheep’s row in a Trigger reply.

DogSectionToml

A dog’s [dog.<name>] config section, carried as TOML text.

Envelope

A request frame

ExitInfo

Why a sheep’s process most recently stopped existing under this daemon.

Hello

Client’s opening frame

HelloAck

Daemon’s handshake answer

Lamb

One process the OS reports as a descendant of a sheep.

LineReply

One matched sheep’s row in a SendLine reply.

ProcessInfo

Snapshot of one sheep for listings and events #[non_exhaustive]: this struct has now grown a field in five separate phases (out_file/err_file, then cpu_percent/memory_bytes, then dog, then lambs, then last_exit) with no hand-edit sweep across the workspace for any of them — the attribute is paying for itself exactly as advertised. Corrected from an earlier version of this comment, which overstated deferred.md’s own ProcessInfo entry as a warning against growing this struct at all: what that entry actually defers is SPLITTING it into several smaller types, and calls this attribute plus ProcessInfo::builder “deliberately the opposite of forcing the split early” — i.e. exactly what makes a field like last_exit cheap to add for a concrete operator need, not a reason to withhold one. Use ProcessInfo::builder to construct one; the fields stay pub, so reading them and assigning to them are both unchanged.

ProcessInfoBuilder

Builds a ProcessInfo, which is #[non_exhaustive] and so cannot be written as a struct literal outside this crate.

Reply

A reply frame

RpcError

Structured RPC failure

SignalReply

One matched sheep’s row in a Signal reply.

Smit

A short marker a dog attaches to a sheep for shep flock to paint.

Enums

ActionOutcome

What happened when the daemon tried to deliver one sheep’s triggered action.

DogSource

Where a dog came from: this binary, or one an operator adopted.

LineOutcome

What happened when the shepherd tried to write one line to a sheep’s stdin.

Request

One RPC request (Phase 1 verb set; later phases extend)

Response

One RPC response (pairs with Request variants)

RpcErrorCode

Machine-readable RPC error codes

SelectorSpec

Serializable selector (mirror of crate::selector::ProcessSelector; regex travels as its source string)

SignalOutcome

What happened when the shepherd tried to deliver one signal.

SmitError

Why a string is not a Smit.

Type Aliases

HelloReply

Handshake outcome: HelloAck or a typed refusal (spec §6 — version skew is an error, not silence). Same Ok/Err wire shape as Reply::result; refusals use RpcErrorCode::ProtocolMismatch.
