Enum NeverEnoughTokensError 

pub enum NeverEnoughTokensError {
    ExceedsMaxTokens,
    ZeroRate,
    InstantNotRepresentable,
}

The token bucket will never have the requested number of tokens.

Variants

ExceedsMaxTokens

The request exceeds the bucket’s maximum number of tokens.

ZeroRate

The refill rate is 0.

InstantNotRepresentable

The time is not representable.

For example the if the rate is low and a large number of tokens were requested, it may be too far in the future that it cannot be represented as a time value.

Trait Implementations

impl Clone for NeverEnoughTokensError

fn clone(&self) -> NeverEnoughTokensError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NeverEnoughTokensError

impl Debug for NeverEnoughTokensError

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

Formats the value using the given formatter.

impl Eq for NeverEnoughTokensError

impl Error for NeverEnoughTokensError

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 NeverEnoughTokensError

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