Enum HllError 

#[non_exhaustive]
pub enum HllError {
    PrecisionMismatch {
        left: u32,
        right: u32,
    },
    InvalidPrecision(u32),
    BadMagic,
    UnsupportedVersion(u8),
    UnsupportedEncoding(u8),
    Truncated {
        expected: usize,
        actual: usize,
    },
}

Every failure subms-hyperloglog can return.

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.

PrecisionMismatch

Two sketches at different precisions cannot be reconciled: the register index is cut from a different slice of the hash.

Fields

left: u32

right: u32

InvalidPrecision(u32)

Precision outside the calibrated [4, 18] range.

BadMagic

Buffer does not start with the SHLL magic.

UnsupportedVersion(u8)

Format version this build does not understand.

UnsupportedEncoding(u8)

Encoding byte this build does not understand, or one the target type refuses (a sparse buffer handed to HyperLogLog::from_bytes).

Truncated

Buffer ended before the declared payload did.

Fields

expected: usize

actual: usize

Trait Implementations

impl Eq for HllError

impl Error for HllError

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 HllError

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

Equality operator ==.

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

Inequality operator !=.
