Expand description
The possible types a SCALE encodable Rust value could have.
Note
In order to preserve backwards compatibility, variant indices are explicitly specified instead of depending on the default implicit ordering.
When adding a new variant, it must be added at the end with an incremented index.
When removing an existing variant, the rest of variant indices remain the same, and the removed index should not be reused.
Variants
Composite(TypeDefComposite<T>)
A composite type (e.g. a struct or a tuple)
Variant(TypeDefVariant<T>)
A variant type (e.g. an enum)
Sequence(TypeDefSequence<T>)
A sequence type with runtime known length.
Array(TypeDefArray<T>)
An array type with compile-time known length.
Tuple(TypeDefTuple<T>)
A tuple type.
Primitive(TypeDefPrimitive)
A Rust primitive type.
Compact(TypeDefCompact<T>)
A type using the [Compact
] encoding
BitSequence(TypeDefBitSequence<T>)
A type representing a sequence of bits.
