Enum DpError 

pub enum DpError {
    BudgetExhausted {
        remaining: f64,
    },
    InvalidParameters(String),
    ZeroSensitivity,
    InvalidEpsilon,
}

Errors produced by differential-privacy operations.

Variants

BudgetExhausted

Privacy budget is fully consumed.

Fields

remaining: f64

Remaining epsilon at the time of the error.

InvalidParameters(String)

A parameter value was semantically invalid.

ZeroSensitivity

Sensitivity was zero or negative, making noise computation impossible.

InvalidEpsilon

Epsilon was zero or negative, making the mechanism undefined.

Trait Implementations

impl Clone for DpError

fn clone(&self) -> DpError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DpError

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

Formats the value using the given formatter.

impl Display for DpError

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

Formats the value using the given formatter.

impl Error for DpError

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.
