Enum FunctionArgExpr 

pub enum FunctionArgExpr {
    Expr(Expr),
    QualifiedWildcard(ObjectName),
    Wildcard,
    WildcardWithOptions(WildcardAdditionalOptions),
}

Expression forms allowed as a function argument.

Variants

Expr(Expr)

A normal expression argument.

QualifiedWildcard(ObjectName)

Qualified wildcard, e.g. alias.* or schema.table.*.

Wildcard

An unqualified * wildcard.

WildcardWithOptions(WildcardAdditionalOptions)

An unqualified * wildcard with additional options, e.g. * EXCLUDE(col).

Used in Snowflake to support expressions like HASH(* EXCLUDE(col)).

Trait Implementations

impl Clone for FunctionArgExpr

fn clone(&self) -> FunctionArgExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionArgExpr

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

Formats the value using the given formatter.

impl Display for FunctionArgExpr

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

Formats the value using the given formatter.

impl Eq for FunctionArgExpr

impl From<Expr> for FunctionArgExpr

fn from(wildcard_expr: Expr) -> FunctionArgExpr

Converts to this type from the input type.

impl Hash for FunctionArgExpr

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 FunctionArgExpr

fn cmp(&self, other: &FunctionArgExpr) -> 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 FunctionArgExpr

fn eq(&self, other: &FunctionArgExpr) -> 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 FunctionArgExpr

fn partial_cmp(&self, other: &FunctionArgExpr) -> 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 FunctionArgExpr

partial span

Missing spans:

• FunctionArgExpr::Wildcard
• FunctionArgExpr::WildcardWithOptions

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 FunctionArgExpr

impl Visit for FunctionArgExpr

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 FunctionArgExpr

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

where V: VisitorMut,

Mutably visit this node with the provided VisitorMut.
