pub struct ReadableProcessByte { /* private fields */ }Expand description
Read-only wrapper around a Cell
This type is used in providing the ReadableProcessSlice. The
memory over which a ReadableProcessSlice exists must never be
written to by the kernel. However, it may either exist in flash
(read-only memory) or RAM (read-writeable memory). Consequently, a
process may allow memory overlapping with a
ReadOnlyProcessBuffer also simultaneously through a
ReadWriteProcessBuffer. Hence, the kernel can have two
references to the same memory, where one can lead to mutation of
the memory contents. Therefore, the kernel must use Cells
around the bytes shared with userspace, to avoid violating Rust’s
aliasing rules.
This read-only wrapper around a Cell only exposes methods
which are safe to call on a process-shared read-only allow
memory.
