Struct Region 

pub struct Region {
    pub base: u64,
    pub size: u64,
    pub read: bool,
    pub write: bool,
    pub execute: bool,
    pub atomic: bool,
    pub width: Option<u64>,
}

A range of physical addresses and what it may be used for: its physical memory attributes. An access outside every region, or one its region does not permit, is an access fault before it reaches the bus — so a device register is never fetched from, never the target of an atomic, and never read or written in part. These attributes are the only source of access faults: every access they permit, the bus completes.

Fields

base: u64

size: u64

read: bool

write: bool

execute: bool

atomic: bool

width: Option<u64>

Every access must be exactly this many bytes (device registers are whole words).

Implementations

impl Region

pub const fn memory(base: u64, size: u64) -> Self

Memory: every kind of access.

pub const fn data(base: u64, size: u64) -> Self

Memory that holds data and never code.

pub const fn rom(base: u64, size: u64) -> Self

Read-only memory that holds code.

pub const fn io(base: u64, size: u64) -> Self

Device registers: whole-word loads and stores only.

Trait Implementations

impl Clone for Region

fn clone(&self) -> Region

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Region

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

Formats the value using the given formatter.

impl PartialEq for Region

fn eq(&self, other: &Region) -> 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 Copy for Region
