Introduces TypeWithDefault<T, D: Get<T>>
#4034
Conversation
Because we like different implementations, I came up with another one :D #4044 (which should be actually the one that requires the least changes) |
Yeah, yours is much simpler :)) |
NonceWithDefault<D: Get<N>, N: Nonce>
TypeWithDefault<T, D: Get<T>>

I am still a bit unsure about the technicality of all the trait impls that are added, but in general looks good as it solves a security issue.

//! Provides a type that wraps another type and provides a default value. |

DQ but it wraps a value, not a type, or?

Maybe ValueWithDefault<T, D: Get<T>>
?

It's actually a type. For example, the mock is wrapping |
But it does also contain a value |

Needed for: polkadot-fellows/runtimes#248 This PR introduces a new type `TypeWithDefault<T, D: Get<T>>` to be able to provide a custom default for any type. This can, then, be used to provide the nonce type that returns the current block number as the default, to avoid replay of immortal transactions. --------- Co-authored-by: Oliver Tale-Yazdi <[email protected]>

Crucially, this type should have not derived TypeInfo
. It should have had a manual TypeInfo
implementation that would mimic the internal T
.
