impl ExtendedCatalog

pub fn new() -> Self

pub fn register_decoder<D: CustomDecoder + 'static>(&mut self, decoder: D)

Register a custom decoder.

pub fn register_descriptor(&mut self, descriptor: ArtifactDescriptor)

Register a custom artifact descriptor.

pub fn by_id(&self, id: &str) -> Option<&ArtifactDescriptor>

Look up an artifact descriptor by ID, checking custom descriptors first.

pub fn len(&self) -> usize

Returns the total number of descriptors (base + custom).

pub fn is_empty(&self) -> bool

Returns true if there are no descriptors.

pub fn custom_decoder(&self, id: &str) -> Option<&dyn CustomDecoder>

pub fn custom_decoder_count(&self) -> usize

Returns the number of registered custom decoders.

pub fn custom_descriptor_count(&self) -> usize

Returns the number of registered custom descriptors.
