Struct ModelLimitsRegistry 

pub struct ModelLimitsRegistry { /* private fields */ }

Registry for model limits with built-in defaults and user overrides.

Implementations

impl ModelLimitsRegistry

pub fn new() -> Self

Create a new registry with built-in defaults only.

pub fn with_config_path(path: impl Into<PathBuf>) -> Self

Create a registry with a specific config file path.

pub async fn load_user_config(&mut self) -> Result<()>

Load user overrides from the registry’s configured path.

No-op when the registry was created without a config_path (use Self::with_config_path — e.g. with get_default_config_path — to point it at {bamboo_data_dir}/model_limits.json).

pub fn add_limit(&mut self, limit: ModelLimit)

Add a user limit override.

pub fn get(&self, model: &str) -> Option<ModelLimit>

Get limit for a model, with user overrides taking priority.

Returns None if no matching limit is found.

Matching Strategy

1. Exact match (highest priority)
2. Model contains pattern (e.g., “gpt-4o-mini” contains “gpt-4o”)

For partial matches, the longest (most specific) pattern wins.

Only the model.contains(pattern) direction is correct: the configured pattern must be a substring of the runtime model id. The reverse (pattern.contains(model)) was a bug (#20, bug 3) — it let a short model id like "gpt-4o" match a longer, unrelated pattern like "gpt-4o-mini" and inherit the wrong limit.

pub fn get_or_default(&self, model: &str) -> ModelLimit

Get limit for a model with fallback to default.

pub async fn save_user_config(&self) -> Result<()>

Save current user limits to the configured file.

No-op when the registry has no config_path.

pub fn list_user_limits(&self) -> Vec<&ModelLimit>

List all user-defined limits.
