Canonical event types for all adapters.

This enum unifies server, download, and model events into a single discriminated union. Each variant includes all necessary context for the event to be self-describing.

Variants

ServerStarted

A model server has started and is ready to accept requests.

Fields

model_id: i64

ID of the model being served.

model_name: String

Name of the model being served.

port: u16

Port the server is listening on.

ServerStopped

A model server has been stopped (clean shutdown).

Fields

model_id: i64

ID of the model that was being served.

model_name: String

Name of the model that was being served.

ServerError

A model server encountered an error.

Fields

model_id: Option<i64>

ID of the model being served (if known).

model_name: String

Name of the model being served.

error: String

Error description.

ServerSnapshot

Snapshot of all currently running servers.

Fields

servers: Vec<ServerSnapshotEntry>

List of currently running servers.

Download

Download lifecycle + progress events (including shard progress).

Wraps DownloadEvent verbatim to preserve all detail including shard-specific progress information.

Fields

event: DownloadEvent

The download event payload.

ModelAdded

A model was added to the library.

Fields

model: ModelSummary

Summary of the added model.

ModelRemoved

A model was removed from the library.

Fields

model_id: i64

ID of the removed model.

ModelUpdated

A model was updated in the library.

Fields

model: ModelSummary

Summary of the updated model.

ServerHealthChanged

Server health status has changed.

Emitted by continuous monitoring when a server’s health state changes.

Fields

server_id: i64

Unique server instance identifier.

model_id: i64

ID of the model being served.

status: ServerHealthStatus

New health status.

detail: Option<String>

Optional detail message (e.g., error description).

timestamp: u64

Unix timestamp in milliseconds when status changed.

McpServerAdded

An MCP server was added to the configuration.

Fields

server: McpServerSummary

Summary of the added server.

McpServerRemoved

An MCP server was removed from the configuration.

Fields

server_id: i64

ID of the removed server.

McpServerStarted

An MCP server has started and is ready.

Fields

server_id: i64

ID of the server.

server_name: String

Name of the server.

McpServerStopped

An MCP server has been stopped.

Fields

server_id: i64

ID of the server.

server_name: String

Name of the server.

McpServerError

An MCP server encountered an error.

Fields

error: McpErrorInfo

User-safe error information.
