    pub action: MergeAction,
}

fn clone(&self) -> MergeWhenClause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl PartialEq for MergeWhenClause

fn eq(&self, other: &MergeWhenClause) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
