    Unavailable,
    InvalidCounter,
    UnsupportedEvent,
    InvalidConfiguration,
    InvalidPeriod,
}

Available on AArch64 and crate feature pmu only.

A requested PMU operation could not be performed.

Variants

Unavailable

This CPU does not implement architectural PMUv3.

InvalidCounter

The counter index is not implemented on this CPU.

UnsupportedEvent

The event is architecturally reported as unsupported.

InvalidConfiguration

The configuration does not apply to the selected counter.

InvalidPeriod

The requested period is zero or exceeds the active counter width.

Trait Implementations

impl Eq for PmuError

impl Error for PmuError

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 PartialEq for PmuError

fn eq(&self, other: &PmuError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool
