Struct scale_info::PortableRegistryBuilder

pub struct PortableRegistryBuilder { /* private fields */ }

Construct a PortableRegistry.

Guarantees that the resulting PortableRegistry has the list of types in the correct order, since downstream libs assume that a u32 type id corresponds to the index of the type definition type table.

Implementations

impl PortableRegistryBuilder

pub fn new() -> Self

Create a new PortableRegistryBuilder.

If the type is already registered it will return the existing ID.

pub fn next_type_id(&self) -> u32

Returns the type id that would be assigned to a newly registered type.

pub fn get(&self, id: u32) -> Option<&Type<PortableForm>>

Returns a reference to the type registered at the given ID (if any).

pub fn finish(&self) -> PortableRegistry

Finalize and return a valid PortableRegistry instance.
