```rust
pub comptime struct TypeGeneric
{ /* private fields */ }
```

A generic parameter of a [`TypeDefinition`](/aztec-nr-api/v6.0.0/std/primitive.TypeDefinition.md), returned from [`TypeDefinition::generics`](/aztec-nr-api/v6.0.0/std/primitive.TypeDefinition.md#generics).

## Implementations

```rust
impl TypeGeneric
```

```rust
