Enum DeserializeError

        got: usize,

}

Error returned when deserializing a byte slice into an ExaLogLog sketch.

Variants

TooShort

Byte slice is shorter than the minimum header length.

Fields

got: usize

Bytes received.

need: usize

Bytes required (at minimum).

BadMagic

Magic prefix did not match.

UnsupportedVersion(u8)

Format version is not supported by this build.

ParameterMismatch

The encoded t or d parameter does not match what this type expects. ExaLogLog accepts (t=2, d=20); ExaLogLogFast accepts (t=2, d=24).

Fields

t: u8

Encoded t.

d: u8

Encoded d.

InvalidPrecision(u8)

Encoded p is outside the supported range.

LengthMismatch

Length of the byte slice does not match what p implies.

Fields

got: usize

Bytes received.

expected: usize

Bytes expected, given the encoded p.

Trait Implementations

impl Debug for DeserializeError

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

Formats the value using the given formatter.

impl Display for DeserializeError

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

Formats the value using the given formatter.

impl Error for DeserializeError

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 DeserializeError

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