Module Shared 

Module-private state for the Vine client: connection pool, per- connection metadata, the broadcast fan-out, the shutdown flag, plus the constants and message-size validator that every entry-point shares.

Structs

CONNECTION_METADATA

ConnectionMetadata

Connection metadata tracking health and last activity.

NOTIFICATION_BROADCAST

SIDECAR_CLIENTS

Constants

CONNECTION_TIMEOUT_MS

Connection timeout (currently unused - kept for the streaming variant).

DEFAULT_TIMEOUT_MS

Default timeout for RPC calls.

HEALTH_CHECK_INTERVAL_MS

Health-check interval.

MAX_MESSAGE_SIZE_BYTES

Maximum message size for validation (4 MB to match the tonic default).

MAX_RETRY_ATTEMPTS

Maximum number of retry attempts for failed connections.

NOTIFICATION_BROADCAST_CAPACITY

Notification broadcast capacity (drop-oldest when full). 4096 covers the worst-case storms (sky://diagnostics/changed at 50-200/s during rust-analyzer cargo-check) with margin.

RETRY_BASE_DELAY_MS

Base delay between retry attempts.

Statics

SHUTDOWN_FLAG

Process-wide shutdown flag. Set to true once Mountain has issued $shutdown (or SIGKILL’d) Cocoon. After that point all SendNotification / SendRequest calls short-circuit.

Functions

RecordSideCarFailure

Increment the failure counter and mark the connection unhealthy.

ShutdownFlagLoad

ShutdownFlagStore

UpdateSideCarActivity

Refresh the last-activity timestamp and reset the failure counter.

ValidateMessageSize

Reject messages above MAX_MESSAGE_SIZE_BYTES to bound the worst-case gRPC frame. Mirrors tonic’s own check so we don’t pay the codec round- trip for an oversize payload.

Type Aliases

CocoonClient

Cocoon gRPC client over a tonic transport channel.
