}Expand description
Trait for fallible conversions between bnum integer types.
Unfortunately, TryFrom cannot currently be used for conversions between bnum integers, since TryFrom<T> for T is already implemented by the standard library (and so it is not possible to implement TryFrom<BUint<M>> for BUint<N>). When the generic_const_exprs feature becomes stabilised, it may be possible to use TryFrom instead of BTryFrom. BTryFrom is designed to have the same behaviour as TryFrom for conversions between two primitive types, and conversions between a primitive type and a bnum type. BTryFrom is a workaround for the issue described above, and so you should not implement it yourself. It should only be used for conversions between bnum integers.
