Implementations

impl CodeConfig

pub fn new() -> Self

Create a new empty configuration

pub fn from_file(path: &Path) -> Result<Self>

Load configuration from an ACL-compatible config file.

.acl is the only supported config file extension. JSON and legacy .hcl config files are not supported.

pub fn from_acl(content: &str) -> Result<Self>

Parse configuration from an ACL string.

ACL (Agent Configuration Language) uses labeled blocks like providers "openai" { }.

pub fn find_provider(&self, name: &str) -> Option<&ProviderConfig>

Find a provider by name

pub fn default_provider_config(&self) -> Option<&ProviderConfig>

Get the default provider configuration (parsed from default_model “provider/model” format)

pub fn default_model_config(&self) -> Option<(&ProviderConfig, &ModelConfig)>

Get the default model configuration (parsed from default_model “provider/model” format)

pub fn default_llm_config(&self) -> Option<LlmConfig>

Get LlmConfig for the default provider and model

Returns None if default provider/model is not configured or API key is missing.

pub fn llm_config( &self, provider_name: &str, model_id: &str, ) -> Option<LlmConfig>

Get LlmConfig for a specific provider and model

Returns None if provider/model is not found or API key is missing.

pub fn list_models(&self) -> Vec<(&ProviderConfig, &ModelConfig)>

List all available models across all providers

pub fn add_skill_dir(self, dir: impl Into<PathBuf>) -> Self

Add a skill directory

pub fn add_agent_dir(self, dir: impl Into<PathBuf>) -> Self

Add an agent directory

pub fn has_directories(&self) -> bool

Check if any directories are configured

pub fn has_providers(&self) -> bool

Check if provider configuration is available

Trait Implementations

impl Clone for CodeConfig

fn clone(&self) -> CodeConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CodeConfig

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

Formats the value using the given formatter.

impl Default for CodeConfig

fn default() -> CodeConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CodeConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for CodeConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
