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 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 Eq for FunctionArg

impl StructuralPartialEq for FunctionArg
