Enum bdk_chain::bitcoin::secp256k1::rand::distributions::weighted::WeightedError

pub enum WeightedError {
    NoItem,
    InvalidWeight,
    AllWeightsZero,
    TooMany,
}

Error type returned from WeightedIndex::new.

Variants

NoItem

The provided weight collection contains no items.

InvalidWeight

A weight is either less than zero, greater than the supported maximum, NaN, or otherwise invalid.

AllWeightsZero

All items in the provided weight collection are zero.

TooMany

Too many weights are provided (length greater than u32::MAX)

Trait Implementations

impl Clone for WeightedError

fn clone(&self) -> WeightedError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WeightedError

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

Formats the value using the given formatter.

impl Display for WeightedError

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

Formats the value using the given formatter.

impl Error for WeightedError

fn source(&self) -> Option<&(dyn Error + 'static)>

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 WeightedError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
