Struct Size

pub struct Size(/* private fields */);

Memory region size value (5 bits).

Memory regions must have a size that is a power of two, and their base address must be naturally aligned (ie. aligned to their size).

There is a core-specific minimum size exposed as Mpu::MIN_REGION_SIZE.

pub const S1G: Self

pub const S2G: Self

pub const S4G: Self

The entire 4 GiB memory space.

pub const fn from_raw_bits(bits: u8) -> Self

Creates a Size from a raw 5-bit value.

The bits encode a region size of 2^(bits + 1). For example, a 1 KiB region would use 0b01001 (9): 2^(9+1) = 2^10 = 1024.

pub const fn bits(self) -> u8

Returns the raw 5-bit value encoding the region size.

Trait Implementations

impl Clone for Size

fn clone(&self) -> Size

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Size

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Ord for Size

fn cmp(&self, other: &Size) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Size

fn eq(&self, other: &Size) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Size

fn partial_cmp(&self, other: &Size) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
