Enum FunctionArgExpr

pub enum FunctionArgExpr {
    Expr(Expr),
    ExprQualifiedWildcard(Expr, Vec<Ident>),
    QualifiedWildcard(ObjectName, Option<Vec<Expr>>),
    Wildcard(Option<Vec<Expr>>),
}

Variants

Expr(Expr)

ExprQualifiedWildcard(Expr, Vec<Ident>)

Expr is an arbitrary expression, returning either a table or a column. Idents are the prefix of *, which are consecutive field accesses. e.g. (table.v1).* or (table).v1.*

QualifiedWildcard(ObjectName, Option<Vec<Expr>>)

Qualified wildcard, e.g. alias.* or schema.table.*, followed by optional except syntax

Wildcard(Option<Vec<Expr>>)

An unqualified * or * except (columns)

Trait Implementations

impl Clone for FunctionArgExpr

fn clone(&self) -> FunctionArgExpr

Returns a copy 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

Formats the value using the given formatter.

impl Display for FunctionArgExpr

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

Formats the value using the given formatter.

impl From<WildcardOrExpr> for FunctionArgExpr

fn from(wildcard_expr: WildcardOrExpr) -> Self

Converts to this type from the input type.

impl Hash for FunctionArgExpr

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 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.
