Struct ReconcileOptions 

pub struct ReconcileOptions {
    pub allow_widening: bool,
    pub refuse_on_dropped_column: bool,
}

Options controlling how strict the planner is.

Fields

allow_widening: bool

Allow lossless widening of an existing column (int32→int64→double→string, float→double→string, …). When false, a required widen is refused so an operator must opt in explicitly.

refuse_on_dropped_column: bool

Refuse when the live table has a column the desired schema no longer mentions. When false, an extra live column is left untouched (the additive default — dropping is never automatic regardless).

fn clone(&self) -> ReconcileOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ReconcileOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ReconcileOptions

fn default() -> Self

Conservative defaults: widening is opt-in, extra live columns are tolerated.
