pub(crate) unsafe fn try_cast<A: Copy, B: Copy>(a: A) -> Result<B, PodCastError>
Expand description
Try to cast A
into B
.
Note that for this particular type of cast, alignment isn’t a factor. The input value is semantically copied into the function and then returned to a new memory location which will have whatever the required alignment of the output type is.
§Failure
- If the types don’t have the same size this fails.
