Enum PullCursorError 

#[non_exhaustive]
pub enum PullCursorError {
    Negative,
    ResyncRequired {
        horizon_revision: i64,
    },
}

Reason a pull cursor cannot be served incrementally.

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.

Negative

The cursor is below zero, which no revision counter can produce.

ResyncRequired

The cursor is above zero and below the owner’s purge horizon.

Fields

horizon_revision: i64

The owner’s current purge horizon.

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
