Enum HyperLogLogError 

pub enum HyperLogLogError {
    RegisterSizeTooLarge {
        register_size: usize,
        num_elements: usize,
        hash_bits: u32,

    },
}

Error returned by HyperLogLogBuilder::build when the configuration is invalid.

Variants

RegisterSizeTooLarge

The register size derived from num_elements exceeds the maximum supported by the hash type.

Fields

register_size: usize

num_elements: usize

hash_bits: u32

UnalignedBackend

The estimator size in bits is not divisible by the bit width of the backend word type W, so registers cannot be packed exactly into whole words.

Fields

est_size_in_bits: usize

word_bits: usize

min_alignment: String

min_log2_num_regs: usize

Trait Implementations

impl Clone for HyperLogLogError

fn clone(&self) -> HyperLogLogError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HyperLogLogError

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

Formats the value using the given formatter.

impl Display for HyperLogLogError

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

Formats the value using the given formatter.

impl Error for HyperLogLogError

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.
