Metadata for a single type registered in a TypeRegistry.

Fields

type_id: TypeId

Runtime type identity.

type_name: &'static str

Rust type name for error messages.

push_arg_fn: PushArgFn

Registers a push_arg<T> op at the given argument index.

add_cell_fn: AddCellFn

Creates a sheet cell from a Box<dyn Any> holding a T.

add_source_fn: AddSourceFn

Creates a source-kind sheet cell (via [Sheet::add_source]) from a Box<dyn Any> holding a T.

call_dyn_fn: CallDynFn

Calls DynSegment::call_dyn::<T> and boxes the result.

eq_dyn_fn: fn(&dyn Any, &dyn Any) -> bool

Compares two type-erased values of this type for equality.

default_fn: Option<fn() -> Box<dyn Any>>

Constructs a default T if the type implements Default; otherwise None.

add_conditional_fn: AddConditionalFn

Calls Sheet::add_conditional::<T> with type-erased branch keys.

value_type_fn: fn() -> ValueType

Builds complete concrete leaf metadata with the registered capabilities.
