}Expand description
Equivalent of the Rust core library’s
SliceIndex type for process slices.
This helper trait is used to abstract over indexing operators into
process slices, and is used to “overload” the .get() methods
such that it can be called with multiple different indexing
operators.
While we can use the core library’s SliceIndex trait, parameterized over
our own ProcessSlice types, this trait includes mandatory methods that are
undesirable for the process buffer infrastructure, such as unchecked or
mutable index operations. Furthermore, implementing it requires the
slice_index_methods nightly feature. Thus we vendor our own, small variant
of this trait.
