Enum ThrottleError 

pub enum ThrottleError {
    RequestExceedsCapacity {
        requested: u64,
        capacity: u64,
    },
    ZeroRefillExhausted {
        requested: u64,
        available: u64,
    },
}

Errors returned by Throttle::acquire_blocking.

Variants

RequestExceedsCapacity

The caller asked for more tokens than the bucket can ever hold. Waiting would deadlock; the request must be rejected at the source.

Fields

requested: u64

Tokens the caller asked for.

capacity: u64

Bucket capacity.

ZeroRefillExhausted

The bucket has a zero refill rate and the initial capacity is insufficient for the request. There is no way to ever satisfy the request, so blocking is pointless.

Fields

requested: u64

Tokens the caller asked for.

available: u64

Tokens currently in the bucket.

Trait Implementations

impl Debug for ThrottleError

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

Formats the value using the given formatter.

impl Display for ThrottleError

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

Formats the value using the given formatter.

impl Error for ThrottleError

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 ThrottleError

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