Enum Mutation 

pub enum Mutation {
    Insert {
        table: TableName,
        columns: Vec<ColumnName>,
        input: Box<Rel>,
        conflict: ConflictAction,
        returning: Vec<NamedScalar>,
    },
    Update {
        table: TableName,
        bind: BindingName,
        assignments: Vec<(ColumnName, Scalar)>,
        predicate: Option<Scalar>,
        returning: Vec<NamedScalar>,
    },
    Delete {
        table: TableName,
        bind: BindingName,
        predicate: Option<Scalar>,
        returning: Vec<NamedScalar>,
    },
