Struct AlterFunction 

pub struct AlterFunction {
    pub kind: AlterFunctionKind,
    pub function: FunctionDesc,
    pub aggregate_order_by: Option<Vec<OperateFunctionArg>>,
    pub aggregate_star: bool,
    pub operation: AlterFunctionOperation,
}

ALTER FUNCTION / ALTER AGGREGATE statement.

Fields

kind: AlterFunctionKind

Object type being altered.

function: FunctionDesc

Function or aggregate signature.

aggregate_order_by: Option<Vec<OperateFunctionArg>>

ORDER BY argument list for aggregate signatures.

This is only used for ALTER AGGREGATE.

aggregate_star: bool

Whether the aggregate signature uses *.

This is only used for ALTER AGGREGATE.

operation: AlterFunctionOperation

Operation applied to the object.

Trait Implementations

impl Clone for AlterFunction

fn clone(&self) -> AlterFunction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AlterFunction

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

Formats the value using the given formatter.

impl Display for AlterFunction

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

Formats the value using the given formatter.

impl Eq for AlterFunction

impl From<AlterFunction> for Statement

fn from(a: AlterFunction) -> Statement

Converts to this type from the input type.

impl Hash for AlterFunction

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

where __H: Hasher,

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 Ord for AlterFunction

fn cmp(&self, other: &AlterFunction) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for AlterFunction

fn eq(&self, other: &AlterFunction) -> 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.

impl PartialOrd for AlterFunction

fn partial_cmp(&self, other: &AlterFunction) -> 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.

impl Spanned for AlterFunction

fn span(&self) -> Span

Return the Span (the minimum and maximum Location) for this AST node, by recursively combining the spans of its children.

impl StructuralPartialEq for AlterFunction

impl Visit for AlterFunction

fn visit<V>(&self, visitor: &mut V) -> ControlFlow<<V as Visitor>::Break>

where V: Visitor,

Visit this node with the provided Visitor.

impl VisitMut for AlterFunction

fn visit<V>(&mut self, visitor: &mut V) -> ControlFlow<<V as VisitorMut>::Break>

where V: VisitorMut,

Mutably visit this node with the provided VisitorMut.
