Enum MergeClauseKind 

pub enum MergeClauseKind {
    Matched,
    NotMatched,
    NotMatchedBySource,
}

Which rows trigger a WHEN arm.

Variants

Trait Implementations

impl Clone for MergeClauseKind

fn clone(&self) -> MergeClauseKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MergeClauseKind

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

Formats the value using the given formatter.

impl PartialEq for MergeClauseKind

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

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
