Enum CardinalityError 

pub enum CardinalityError {
    InvalidPrecision,
}

Errors that prevent constructing or updating a HyperLogLog estimator.

Returned (never panicked) so callers stay clear of the crate’s unwrap/panic lint gate and can surface a clean diagnostic.

Variants

InvalidPrecision

The requested precision was outside the supported [4, 18] range, so the register count 2^p and the α_m correction would be ill-defined.

Trait Implementations

impl Clone for CardinalityError

fn clone(&self) -> CardinalityError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CardinalityError

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

Formats the value using the given formatter.

impl Display for CardinalityError

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

Formats the value using the given formatter.

impl Eq for CardinalityError

impl Error for CardinalityError

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 CardinalityError

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