pub struct DryRunResult {
    pub mode: ImportMode,
    pub database_is_empty: bool,
    pub existing_rows: BTreeMap<String, usize>,
    pub would_delete: BTreeMap<String, usize>,

    pub would_succeed: bool,
    pub failure_reason: Option<String>,
    pub warnings: Vec<String>,
}

Result of a dry-run import preview. Shows what would happen without making any changes.

Fields

mode: ImportMode

Import mode that would be used.

database_is_empty: bool

Whether the database is empty (relevant for Fresh mode).

existing_rows: BTreeMap<String, usize>

Number of existing rows per table (before import).

would_delete: BTreeMap<String, usize>

Number of rows that would be deleted per table (Replace mode).

would_insert: BTreeMap<String, usize>

Number of rows that would be inserted per table.

would_skip: BTreeMap<String, usize>

Number of rows that would be skipped per table (Merge mode).

would_succeed: bool

Whether the import would succeed with the given mode.

failure_reason: Option<String>

Reason for failure if would_succeed is false.

warnings: Vec<String>

Any warnings that would be generated.
