Enum EvictError

pub enum EvictError<F: FrameId> {
    InvalidFrameId(F),
    PinnedFrameRemoval(F),
    FrameReplacerFull,
    InvalidTimestamp,
    NoFramesAvailable,

}

Cache eviction policy error.

Variants

InvalidFrameId(F)

Invalid frame id.

PinnedFrameRemoval(F)

Trying to remove pinned frame.

FrameReplacerFull

Cannot add any more pages to the frame replacer.

InvalidTimestamp

Invalid sequence number.

NoFramesAvailable

No free frames available.

SequenceExhausted

Sequence generator arrived at maximum value.

Trait Implementations

impl<F: Debug + FrameId> Debug for EvictError<F>

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

Formats the value using the given formatter.

impl<F> Display for EvictError<F>

where F: Display + FrameId,

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

Formats the value using the given formatter.

impl<F: FrameId> Error for EvictError<F>

where Self: Debug + Display,

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl<F: PartialEq + FrameId> PartialEq for EvictError<F>

fn eq(&self, other: &EvictError<F>) -> 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.
