Struct NullCache 

pub struct NullCache {
    pub last: Option<NullCacheOp>,
}

No-op DcaCache for host tests.

Tracks last-call metadata so tests can assert the right op was emitted at the right transition without a real cache.

Fields

last: Option<NullCacheOp>

Sequence-numbered last operation, useful in unit tests.

Trait Implementations

impl Clone for NullCache

fn clone(&self) -> NullCache

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NullCache

impl DcaCache for NullCache

fn clean(&mut self, addr: usize, len: usize)

Clean (write-back) cache lines covering [addr, addr + len).

fn invalidate(&mut self, addr: usize, len: usize)

Invalidate cache lines covering [addr, addr + len).

fn clean_invalidate(&mut self, addr: usize, len: usize)

Clean+invalidate cache lines covering [addr, addr + len).

fn barrier(&mut self)

Emit a memory barrier sufficient to drain pending writes from the architectural write buffer (the AXI write buffer on Cortex-M7; the equivalent on other targets).

impl Debug for NullCache

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

Formats the value using the given formatter.

impl Default for NullCache

fn default() -> NullCache

Returns the “default value” for a type.

impl Eq for NullCache

impl PartialEq for NullCache

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