Struct CustomDataDecoder 

Source 
pub struct CustomDataDecoder;
Expand description

Decoder for custom data types that are identified at runtime by metadata (e.g. type_name).

Only Rust-registered custom types (e.g. RustTestCustomData, MacroYieldCurveData) can be decoded. Unknown types return an error.

Important: The caller must ensure that any Rust custom data types are registered via ensure_custom_data_registered::<T>() before use.
