Struct AccessSet 

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

The set of accesses which have occurred at this location.

Example

 
let accesses = AccessSet::READ;
assert!(accesses.accessed());
assert!(accesses.read());
assert!(!accesses.written());
assert!(!accesses.modified());

Implementations

impl AccessSet

pub const READ: Self

Set with only the read flag enabled.

pub const WRITTEN: Self

Set with only the write flag enabled.

pub const MODIFIED: Self

Set with only the modify flag enabled.

pub fn accessed(&self) -> bool

True if any access has occurred.

pub fn read(&self) -> bool

True if a read has occurred.

pub fn written(&self) -> bool

True if a write has occurred (does not necessarily have to change data).

pub fn modified(&self) -> bool

True if a write has occurred (data must change).

Trait Implementations

impl BitOr for AccessSet

type Output = AccessSet

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self::Output

Performs the | operation.

impl BitOrAssign for AccessSet

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl Clone for AccessSet

fn clone(&self) -> AccessSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccessSet

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

Formats the value using the given formatter.

impl Default for AccessSet

fn default() -> AccessSet

Returns the “default value” for a type.
