§Mélodium core crate

Core Mélodium components for compiled libraries.

This crate is aimed to be used by compiled Mélodium libraries, in conjuction with melodium-macro.

Core Mélodium types are exposed here, and base descriptors for built-in elements are provided within the descriptor module.

Look at the Mélodium crate or the Mélodium Project for more detailed information.

doc (disabled by default): enables documentation management of elements, when disabled documentation and set_documentation functions will still be present but respectively return empty string and do nothing.

ErasedSerdeError: Error when a Serializer or Deserializer trait object fails.
Lazy: A value which is initialized on the first access.
VecDeque: A double-ended queue implemented with a growable ring buffer.

Data
DataTrait
Deserialize: A data structure that can be deserialized from any data format supported by Serde.
ErasedSerialize: An object-safe equivalent of Serde’s Serialize trait.
ErasedSerializer: An object-safe equivalent of Serde’s Serializer trait.
GetData: Trait allowing to get real data based on Rust type.
InputExt: Pairs recv_one/recv_many with a typed cast, so a mismatch between what a graph wired up and what a treatment expects surfaces as TransmissionError::TypeMismatch instead of requiring every call site to .unwrap() a GetData/TryInto cast by hand (and panic the track on a mismatch). Blanket-implemented for every Input.
OutputExt: Pairs send_one/send_many with the ordinary Into<Value>/From<Vec<T>> conversions, so a treatment sending a plain Rust value never has to name Value/ TransmissionValue itself — symmetric with InputExt::recv_one_as/recv_many_as. Blanket-implemented for every Output.
Serialize: A data structure that can be serialized into any data format supported by Serde.

erased_deserialize: Deserialize a value of type T from the given trait object.
