Enum DeadlineError 

#[non_exhaustive]
pub enum DeadlineError {
    ZeroBudget,
    CapCannotOutlastItsStages {
        open: Duration,
        window: Duration,
        hard_cap: Duration,
    },
}

A PullDeadlines whose bounds cannot do their job. Carries the values so a CLI can render the arithmetic back to the user rather than just saying “invalid”.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ZeroBudget

A zero budget elapses on its first poll, so the stage it bounds can never run.

CapCannotOutlastItsStages

The cap does not outlast open + window, so it always fires first and the throughput floor — the signal that a healthy stream is still making progress — can never fire.

Fields

open: Duration

The open-stage budget.

window: Duration

The throughput-floor window that follows it.

hard_cap: Duration

The whole-pull cap, which must exceed open + window.

impl Eq for DeadlineError

impl Error for DeadlineError

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.
