Enum CounterError 

#[non_exhaustive]
pub enum CounterError {
    NotInvariant,
    NoRate,
    ImplausibleRate {
        hertz: u64,
    },
}

Why Counter::discover found no counter to read as time.

Examples

use t2t_clock::CounterError;

let refusal = CounterError::ImplausibleRate { hertz: 42 };
assert_eq!(
    refusal.to_string(),
    "counter error: a rate of 42 Hz is outside 1 MHz to 10 GHz",
    "it names the rate it refused"
);

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotInvariant

The time-stamp counter’s rate follows the core’s, so its ticks have no fixed length.

NoRate

The CPU reports no rate, and none could be measured.

ImplausibleRate

The rate is outside what any counter runs at.

Fields

hertz: u64

The rate the CPU reported, or that was measured, in ticks a second.

impl Eq for CounterError

impl Error for CounterError

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 Hash for CounterError

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 CounterError

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

Equality operator ==.

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

Inequality operator !=.
