Struct FallbackConfig 

pub struct FallbackConfig { /* private fields */ }

Fallback configuration

Manages fallback mappings for different error types. Each model can have different fallback models configured for different scenarios.

Thread Safety

Uses RwLock to allow concurrent reads and exclusive writes.

Implementations

impl FallbackConfig

pub fn new() -> Self

Create a new empty fallback configuration

pub fn add_general(self, model: &str, fallbacks: Vec<String>) -> Self

Add general fallback models for a model (builder pattern)

General fallbacks are used when no specific fallback type matches the error.

Panics

Panics if the internal lock is poisoned (indicates a bug in the calling code).

pub fn add_context_window(self, model: &str, fallbacks: Vec<String>) -> Self

Add context window fallback models for a model (builder pattern)

Context window fallbacks are used when the input exceeds the model’s maximum context length.

Panics

Panics if the internal lock is poisoned (indicates a bug in the calling code).

pub fn add_content_policy(self, model: &str, fallbacks: Vec<String>) -> Self

Add content policy fallback models for a model (builder pattern)

Content policy fallbacks are used when content is filtered or rejected by safety systems.

Panics

Panics if the internal lock is poisoned (indicates a bug in the calling code).

pub fn add_rate_limit(self, model: &str, fallbacks: Vec<String>) -> Self

Add rate limit fallback models for a model (builder pattern)

Rate limit fallbacks are used when the model’s rate limit is exceeded.

Panics

Panics if the internal lock is poisoned (indicates a bug in the calling code).

pub fn get_fallbacks_for_type( &self, model_name: &str, fallback_type: FallbackType, ) -> Vec<String>

Get fallback models for a specific type

Returns a cloned vector of fallback model names. Returns empty vector if no fallbacks are configured for the given model and type.

Panics

Panics if the internal lock is poisoned (indicates a bug in the calling code).

Trait Implementations

impl Debug for FallbackConfig

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

Formats the value using the given formatter.

impl Default for FallbackConfig

fn default() -> FallbackConfig

Returns the “default value” for a type.
