Struct MergeIntoOp 

pub struct MergeIntoOp {
    pub on: Expr,
    pub clauses: Vec<MergeIntoClause>,
}

Describes a MERGE INTO operation’s parameters.

Fields

on: Expr

The join condition from ON <expr>.

clauses: Vec<MergeIntoClause>

The WHEN clauses, in the order they appeared in the SQL.

Implementations

impl MergeIntoOp

pub fn exprs(&self) -> Vec<&Expr>

Top-level Exprs in stable order: on, then per-clause predicate (if any) and action value expressions.

pub fn with_new_exprs(&self, exprs: Vec<Expr>) -> Result<Self>

Rebuild this MergeIntoOp from a flat vector of new expressions, in the same order produced by Self::exprs. The clause kinds, action kinds, column lists, and presence/absence of each predicate are preserved from self.

Trait Implementations

impl Clone for MergeIntoOp

fn clone(&self) -> MergeIntoOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MergeIntoOp

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

Formats the value using the given formatter.

impl Eq for MergeIntoOp

impl Hash for MergeIntoOp

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MergeIntoOp

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for MergeIntoOp

fn partial_cmp(&self, other: &MergeIntoOp) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
