Struct ModelSpec 

pub struct ModelSpec {
    pub key: String,
    pub api_id: String,
    pub protocol: Protocol,
    pub thinking: ThinkingMode,
    pub context_window_tokens: u64,
    pub max_image_base64_bytes: u64,
    pub max_truncated_resumes: u32,
    pub auto_compact_at_tokens: Option<u64>,
}

A resolved model: everything the protocol drivers need, minus credentials (those live in BackendConfig). Built by the application configuration from the [models] / [gateways] catalog in config.toml — myco ships no built-in models.

Fields

key: String

Catalog key: what the user types after --model and what sessions record. Distinct from api_id so one wire model can appear under several keys (e.g. routed via different gateways).

api_id: String

Wire id sent to the provider (the request model field).

protocol: Protocol

thinking: ThinkingMode

context_window_tokens: u64

Context window for UX (USER n/m) and auto-compact heuristics.

max_image_base64_bytes: u64

Largest image this model accepts, measured on the base64 payload. Enforced locally by view_image and by REPL @path attachments so an oversized image fails with a clear message instead of a provider 400. Always concrete: config resolution applies the max_image_base64_bytes entry or its default, and callers downstream take this value.

max_truncated_resumes: u32

How many consecutive max_tokens truncations one turn resumes through before handing control back (0 never resumes). Resolved from the model’s max_truncated_resumes or its default; the agent takes this value via the agent’s continuation policy.

auto_compact_at_tokens: Option<u64>

Prompt size at which the REPL compacts without being asked. None = no auto-compaction (the default; /compact still works).

Resolved from the model’s auto_compact_at fraction against context_window_tokens so the comparison downstream is a plain token count, and the fraction is validated once, at startup.

Trait Implementations

impl Clone for ModelSpec

fn clone(&self) -> ModelSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModelSpec

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

Formats the value using the given formatter.

impl Display for ModelSpec

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

Formats the value using the given formatter.

impl Eq for ModelSpec

impl PartialEq for ModelSpec

fn eq(&self, other: &ModelSpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
