Enum SketchError 

pub enum SketchError {
    InvalidConfig(String),
    Deserialization(String),
    Cpp(String),
    EmptyIntersection,
}

Error type shared across all sketch families (HLL, Theta, CPC) in this crate — there is no per-family error type.

Variants

InvalidConfig(String)

A builder or constructor was given an out-of-range configuration value (e.g. lg_k/lg_config_k outside its valid bounds, or a num_std_dev outside 1..=3). The underlying C++ layer rejected the value; the string is its exception message.

Deserialization(String)

deserialize/deserialize_compressed/wrap was given bytes that don’t parse as a valid serialized sketch (e.g. truncated, corrupt, or produced by an incompatible seed).

Cpp(String)

A catch-all for any other C++ exception that crossed the FFI boundary, carrying its what() message. Prefer matching on a more specific variant above when one applies.

EmptyIntersection

ThetaIntersection::get_result() was called before any update().

Trait Implementations

impl Debug for SketchError

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

Formats the value using the given formatter.

impl Display for SketchError

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

Formats the value using the given formatter.

impl Error for SketchError

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 From<Exception> for SketchError

fn from(e: Exception) -> Self

Converts to this type from the input type.
