Struct AdapterRegistry 

pub struct AdapterRegistry<A>
where
    A: Adapter,
{ /* private fields */ }

Registry for managing multiple named adapters.

Allows switching between different adapters at runtime.

Note: Adapter composition (combining multiple adapters) is planned for a future release.

Implementations

impl<A> AdapterRegistry<A>

where A: Adapter,

pub fn new() -> AdapterRegistry<A>

Create a new empty adapter registry.

pub fn register_adapter( &mut self, name: impl Into<String>, adapter: A, ) -> Result<(), PeftError>

Register a new adapter with the given name.

Arguments

• name - Unique name for the adapter
• adapter - The adapter to register

Errors

Returns an error if an adapter with this name already exists

pub fn set_active_adapter( &mut self, name: impl Into<String>, ) -> Result<(), PeftError>

Set the active adapter by name.

Arguments

• name - Name of the adapter to activate

Errors

Returns an error if no adapter with this name exists

pub fn get_active_adapter(&self) -> Result<&A, PeftError>

Get a reference to the active adapter.

Errors

Returns an error if no adapter is currently active

pub fn get_active_adapter_mut(&mut self) -> Result<&mut A, PeftError>

Get a mutable reference to the active adapter.

Errors

Returns an error if no adapter is currently active

pub fn get_adapter(&self, name: &str) -> Result<&A, PeftError>

Get a reference to an adapter by name.

Arguments

• name - Name of the adapter

Errors

Returns an error if no adapter with this name exists

pub fn get_adapter_mut(&mut self, name: &str) -> Result<&mut A, PeftError>

Get a mutable reference to an adapter by name.

Arguments

• name - Name of the adapter

Errors

Returns an error if no adapter with this name exists

pub fn contains_adapter(&self, name: &str) -> bool

Check if an adapter with the given name exists.

pub fn active_adapter_name(&self) -> Option<&str>

Get the name of the currently active adapter.

pub fn adapter_names(&self) -> Vec<&str>

Get a list of all registered adapter names.

pub fn len(&self) -> usize

Get the number of registered adapters.

pub fn is_empty(&self) -> bool

Check if the registry is empty.

pub fn remove_adapter(&mut self, name: &str) -> Result<Option<A>, PeftError>

Remove an adapter by name.

Arguments

• name - Name of the adapter to remove

Returns

The removed adapter, if it existed

Errors

Returns an error if trying to remove the active adapter

pub fn clear(&mut self)

Clear all adapters from the registry.

pub fn forward( &self, input: &Tensor, base_output: Option<&Tensor>, ) -> Result<Tensor, PeftError>

Apply the active adapter to an input tensor.

Arguments

• input - Input tensor
• base_output - Optional base layer output

Errors

Returns an error if no active adapter or forward pass fails

Trait Implementations

impl<A> Default for AdapterRegistry<A>

where A: Adapter,

fn default() -> AdapterRegistry<A>

Returns the “default value” for a type.
