# AbiValueType

Defined in: [metacomputer/gen-framework/client-and-test-utils/client-sdk-ts/packages/client-sdk/src/rpc-types/types.ts:29](https://github.com/gen-bc/gen/blob/main/metacomputer/gen-framework/client-and-test-utils/client-sdk-ts/packages/client-sdk/src/rpc-types/types.ts#L29)

Structured representation for any value type used by ABI elements or type definitions.

Named-field structs are represented as Struct variants with AbiStructDef fields. Unnamed-field (tuple) structs are represented as Tuple variants, one entry per field.

A single-field tuple struct (newtype) appears as a 1-element `Tuple` in type definitions. When `resolve_named_types` expands a chain of newtypes (e.g. `EntityId(H256(PTH256([u8; 32])))`) the nested single-element Tuples are collapsed to a single Tuple wrapping the leaf type.
