Enum FunctionArg 

pub enum FunctionArg {
    Named {
        name: Ident,
        arg: FunctionArgExpr,
        operator: FunctionArgOperator,
    },
    ExprNamed {
        name: Expr,
        arg: FunctionArgExpr,
        operator: FunctionArgOperator,
    },
    Unnamed(FunctionArgExpr),
}

Forms of function arguments (named, expression-named, or positional).

Variants

Named

name is identifier

Enabled when Dialect::supports_named_fn_args_with_expr_name returns ‘false’

Fields

name: Ident

The identifier name of the argument.

arg: FunctionArgExpr

The argument expression or wildcard form.

operator: FunctionArgOperator

The operator separating name and value.

ExprNamed

name is arbitrary expression

Enabled when Dialect::supports_named_fn_args_with_expr_name returns ‘true’

Fields

name: Expr

The expression used as the argument name.

arg: FunctionArgExpr

The argument expression or wildcard form.

operator: FunctionArgOperator

The operator separating name and value.

Unnamed(FunctionArgExpr)

An unnamed argument (positional), given by expression or wildcard.

Trait Implementations

impl Clone for FunctionArg

fn clone(&self) -> FunctionArg

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionArg

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

Formats the value using the given formatter.

impl Display for FunctionArg

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

Formats the value using the given formatter.

impl Eq for FunctionArg

impl Hash for FunctionArg

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 FunctionArg

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

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

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

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 FunctionArg

impl Visit for FunctionArg

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 FunctionArg

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

where V: VisitorMut,

Mutably visit this node with the provided VisitorMut.
