Struct voladdress::VolBlock

#[repr(transparent)]pub struct VolBlock<T, R, W, const C: usize> { /* fields omitted */ }

A volatile memory block.

This is intended to model when a portion of memory is an array of identical values in a row, such as a block of 256 u16 values in a row.

Generic Parameters

• T / R / W: These parameters are applied to the VolAddress type returned when accessing the block in any way (indexing, iteration, etc).
• C: the count of elements in the block.

Safety

• This type stores a base VolAddress internally, and so you must follow all of those safety rules. Notably, the base address must never be zero.
• The address space must legally contain C contiguous values of the T type, starting from the base address.
• The memory block must not wrap around past the end of the address space.

Implementations

impl<T, R, W, const C: usize> VolBlock<T, R, W, C>

#[must_use]pub const unsafe fn new(base: usize) -> Self

Constructs the value.

Safety

• As per the type docs.

#[must_use]pub const unsafe fn len(self) -> usize

The length of this block (in elements).

#[must_use]pub const fn index(self, i: usize) -> VolAddress<T, R, W>

Indexes to the ith position of the memory block.

Panics

• If the index is out of bounds this will panic.

#[must_use]pub const fn get(self, i: usize) -> Option<VolAddress<T, R, W>>

Gets the address of the ith position, if it’s in bounds.

#[must_use]pub const fn iter(self) -> VolBlockIter<T, R, W>

Creates an iterator over the addresses of the memory block.
