Crate scv_client 

What every local client of the SCV daemon needs, without depending on the server: the instance Layout (every path under SCV_HOME, and the instance’s service unit name), the delegation-depth variable a delegated SCV inherits, framed reading and writing (Connection, read_frame), private instance files (fs::replace_private), Secret values that never print, byte-bounded text (text::utf8_prefix), and control for daemon management requests, which fail with a typed ControlError.

Modules

fs

Private instance files: SCV’s state, records, and credentials are written whole, readable only by the user, and survive a crash.

text

Byte-bounded text, for limits that count bytes on the wire or on disk.

Structs

Connection

A client’s side of one protocol connection: a buffered reader, a writer, and the decoder that bounds what the server may send.

Layout

The paths of one SCV instance.

Secret

An API key, token, or app secret.

Stray

Something in an instance home that SCV does not read.

Enums

ControlError

Why a control request failed.

Constants

DELEGATION_DEPTH_VARIABLE

Environment variable carrying a delegated process’s depth; SCV sets it on every agent it starts.

Functions

control

A bounded management exchange. Never retries mutations on ambiguous failure.

inherited_delegation_depth

The delegation depth to declare in session.start: this process’s own, when an SCV started it, so a delegated client cannot reset the count by connecting to a daemon.

read_frame

Read the next frame from reader.

write_message

Write message as one frame and flush it.
