Enum QuotaError 

pub enum QuotaError {
    SubsCapExceeded {
        have: u32,
        cap: u32,
    },
    RestRateLimit {
        remaining_ms: u64,
    },
    NotInWhitelist(String),
    Inner(StationError),
}

Errors produced by ConsumerHandle operations.

Variants

SubsCapExceeded

The requested subscribe batch would push the consumer over its cap. Nothing in the batch was subscribed (atomic-or-nothing).

Fields

have: u32

cap: u32

RestRateLimit

The consumer’s REST token bucket is empty. remaining_ms is an upper-bound estimate until the next refill.

Fields

remaining_ms: u64

NotInWhitelist(String)

A (exchange, kind, symbol) tuple in the subscribe set was rejected by the consumer’s whitelist. Nothing in the batch was subscribed.

Inner(StationError)

An underlying station error (e.g. StreamNotSupported, IO).

Trait Implementations

impl Debug for QuotaError

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

Formats the value using the given formatter.

impl Display for QuotaError

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

Formats the value using the given formatter.

impl Error for QuotaError

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<StationError> for QuotaError

fn from(source: StationError) -> Self

Converts to this type from the input type.
