Enum rusqlite::backup::StepResult

source · [−]

#[non_exhaustive]
pub enum StepResult {
    Done,
    More,
    Busy,
    Locked,
}

This is supported on crate feature backup only.

Expand description

Possible successful results of calling Backup::step.

Variants (Non-exhaustive)

This enum is marked as 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.

`Done`

The backup is complete.

`More`

The step was successful but there are still more pages that need to be backed up.

`Busy`

The step failed because appropriate locks could not be acquired. This is not a fatal error - the step can be retried.

`Locked`

The step failed because the source connection was writing to the database. This is not a fatal error - the step can be retried.
