}

A single model the kernel knows about: what it is, where it lives, how it runs, and how the user has configured it.

Fields

id: String

Stable identity derived from the source (see stable_id).

name: String

The model’s display name.

modality: Modality

Its primary modality.

capabilities: Vec<Capability>

Everything it can be asked to do.

source: ModelSource

Where its weights live.

runtime: RuntimeRef

The runtime it resolves to.

params: Vec<ParamSpec>

The parameter schema it exposes.

param_values: BTreeMap<String, JsonValue>

User-set parameter values.

system_prompt: Option<String>

A user-set system prompt override.

alias: Option<String>

A user-set display alias.

execution: ExecutionMode

How the runtime delivers output.

footprint_bytes: Option<i64>

What the model’s files take on disk, in bytes, as the store’s scanner measured them. The memory a run needs is estimated from it, not stored.

state: ModelState

The record’s lifecycle state.

registered_at: i64

When the record was first registered, epoch millis.

primary_weight_path: Option<String>

The primary weight file, when one file dominates.

context_length: Option<i64>

The model’s context window, when known.

has_chat_template: Option<bool>

Whether the model ships a chat template.

supports_tools: Option<bool>

Whether the model’s chat template supports tool calling, when it could be read. None means undetermined — treated as capable, gated by a request.

stop_tokens: Option<Vec<String>>

Stop tokens the model declares.

downloading: bool

Whether the model is still downloading.

content_fingerprint: Option<String>

A content fingerprint used to follow a model across moves.

Implementations

impl ModelRecord

pub fn new( name: &str, modality: Modality, capabilities: Vec<Capability>, source: ModelSource, ) -> Self

Create a record for a model, deriving its stable id from source and stamping registered_at with the current time.

pub fn display_name(&self) -> &str

The name to show the user: the alias if set, otherwise the name.

pub fn wire_id(&self) -> &str

The id this model has on the wire: what the gateway’s model listings advertise and what clients send back. One definition, so a launcher that configures a client and the listing it will call cannot disagree. Same rule as display_name, including the empty-alias guard.

pub fn size_on_disk(&self) -> Option<i64>

The size on disk, when one is recorded and positive.

pub fn footprint_mib(&self) -> Option<i64>

The size on disk in whole mebibytes, the unit the memory governor budgets in.

pub fn can(&self, capability: &Capability) -> bool

Whether the model can perform capability.

Trait Implementations

impl Clone for ModelRecord

fn clone(&self) -> ModelRecord

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ModelRecord

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Inequality operator !=.
