Enum MigrationOutcome 

Source 
#[non_exhaustive]
pub enum MigrationOutcome {
    Migrated,
    SkippedBothExist,
    SkippedDestOccupied,
    Failed {
        error: String,
    },
}
Expand description

Outcome of one legacy-layout migration attempt.

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.
§

Migrated

Legacy directory was renamed onto the flat-sibling slot.

§

SkippedBothExist

Both legacy and flat-sibling slots existed. Skipped — the user must inspect and reconcile manually so we never silently delete either.

§

SkippedDestOccupied

Flat-sibling slot already had a non-grex file or directory in the way. Skipped — refusing to clobber user data even when the legacy slot is plainly the source of truth.

§

Failed

fs::rename failed (e.g. cross-volume, ACL denied). The legacy directory is still in place; surfaced so the operator can move it manually.
