Struct scale_info::TypeDefBitSequence

pub struct TypeDefBitSequence<T: Form = MetaForm> { /* private fields */ }

Type describing a [bitvec::vec::BitVec].

Note

This can only be constructed for TypeInfo in the MetaForm with the bit-vec feature enabled, but can be decoded or deserialized into the PortableForm without this feature.

Implementations

impl<T> TypeDefBitSequence<T>where
    T: Form,

pub fn bit_order_type(&self) -> &T::Type

Returns the type of the bit ordering of the [::bitvec::vec::BitVec].

pub fn bit_store_type(&self) -> &T::Type

Returns underlying type used to store the [::bitvec::vec::BitVec].

impl TypeDefBitSequence

pub fn new<Store, Order>() -> Selfwhere
    Store: TypeInfo + 'static,
    Order: TypeInfo + 'static,

Creates a new TypeDefBitSequence for the supplied bit order and bit store types.

With the bit-vec feature enabled, the expected usage is to provide either bitvec::order::Lsb0 or bitvec::order::Msb0 as the order type, and then something like u8, u8, or u32 as the store type. Without the bit-vec feature enabled, it’s recommended that your types have identical TypeInfo to those.

impl TypeDefBitSequence<PortableForm>

pub fn new_portable(
    bit_store_type: <PortableForm as Form>::Type,
    bit_order_type: <PortableForm as Form>::Type
) -> Self

Creates a new TypeDefBitSequence for the supplied bit order and bit store types.
