Question:
What is recommended way to convert one type of uint to another?
Background:
I've developed a high-level lib for creating custom DeFi-oriented types that are implemented in pure Rust, where uint types serve as underlying types.
Details:
In certain scenarios, I need to expand the type to prevent overflow in intermediate calculations. For instance, there are cases where I must extend the type from U256 to U512. I'm exploring the best approach to convert between different uint types.
Based on my observations, it seems that try_from is only implemented for primitive types. One option is to manually rewrite the u64 values, but I believe there might be a more elegant solution. Perhaps it's worth considering the addition of a try_from implementation for converting between types at the uint library level.
As an illustration, consider the following two types:
construct_uint! {
pub struct U256(4);
}
construct_uint! {
pub struct U512(8);
}In this context, creating a U512 type based on a U256 instance could look like this:
U512::try_from(U256::MAX)
Are you willing to help with this request?
I am willing to create a proposal for implementation if the feature is deemed useful.
