Network.Polkadot.Metadata.Type.Ast

Runtime metadata type AST.

typetype QSelf = (TypeAst, TypeAst)

Qualified type parameter, e.g., Vec<T as SomeTrait>::SomeType.

typetype PathSegment = (Text, Maybe [TypeAst])

A segment of a path: an identifier and a set of argument types.

datadata TypeAst

Simple Rust type AST is used for Metadata type representation.

Slice !TypeAst
A variable-length slice ([T]).
Tuple ![TypeAst]
A tuple ((A, B, C, D,...)).
Array !TypeAst !Int
A fixed length array ([T; n]).
Path
- qself :: !Maybe QSelf
  Two types of Vec<T as Trait>.
- segments :: ![PathSegment]
  A segment of a path: an identifier and a set of types.
