Bump, seems like an important fix to merge |
When the slice extends into the uninitialized part of the buffer, the byte slice returned by the Deref and DerefMut impls should always end at the initialized data.
No need for the slice end logic when we only need a pointer to the beginning.
Move the test to integration tests since it only exercises public API. Modify the test to ensure that the size of DerefMut output for Slice is as expected and writing into the slice works.

The
Deref
andDerefMut
impls forSlice
did not ensure that the end of the returned byte slice is clipped to the end of initialized data in the buffer.Fixes #45.
