Enum ConflictResolution 

pub enum ConflictResolution {
    Rollback,
    Abort,
    Fail,
    Ignore,
    Replace,
}

The SQLite OR <action> conflict-resolution algorithm on the mutation verb — INSERT OR {REPLACE | IGNORE | ABORT | FAIL | ROLLBACK} and the same tail on UPDATE. It selects what SQLite does when the statement hits a constraint violation, so it carries genuine new information (which algorithm) rather than a surface spelling; the Insert::or_action / Update::or_action slot models it and the parser gates it on MutationSyntax::or_conflict_action.

This is distinct from two same-named neighbours: it is not the PostgreSQL ConflictAction (the ON CONFLICT DO {NOTHING | UPDATE} upsert action — a different construct in a different clause position, which SQLite also has and which maps to Insert::upsert); and its Replace variant is not the InsertVerb::Replace statement spelling — INSERT OR REPLACE and REPLACE INTO are equivalent SQLite semantics written as different source texts, so each keeps its own representation and round-trips through it (one is never folded onto the other).

Variants

Rollback

OR ROLLBACK — abort the statement and roll back the enclosing transaction.

Abort

OR ABORT — abort the statement, reverting its own prior changes (the default resolution when no OR <action> is written).

Fail

OR FAIL — abort the statement without reverting the rows it already changed.

Ignore

OR IGNORE — skip the offending row and continue the statement.

Replace

OR REPLACE — delete the conflicting rows, then insert/update the new one.
