Enum AccessFlags 

pub enum AccessFlags {
    None,
    Read,
    ReadWrite,
}

Memory access permission flags for virtual memory mappings.

These flags control how a mapped virtual address range can be accessed by a given device.

Variants

None

No access permitted. The mapping exists but cannot be read or written.

Read

Read-only access. The device can read but not write.

ReadWrite

Full read-write access.

Trait Implementations

impl Clone for AccessFlags

fn clone(&self) -> AccessFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccessFlags

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

Formats the value using the given formatter.

impl Default for AccessFlags

fn default() -> AccessFlags

Returns the “default value” for a type.

impl Display for AccessFlags

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

Formats the value using the given formatter.

impl Hash for AccessFlags

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for AccessFlags

fn eq(&self, other: &AccessFlags) -> 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.
