Enum rustc_hir_typeck::TupleArgumentsFlag

pub(crate) enum TupleArgumentsFlag {
    DontTupleArguments,
    TupleArguments,
}

Controls whether the arguments are tupled. This is used for the call operator.

Tupling means that all call-side arguments are packed into a tuple and passed as a single parameter. For example, if tupling is enabled, this function:

fn f(x: (isize, isize)) {}

Can be called as:

f(1, 2);

Instead of:

f((1, 2));

Trait Implementations

impl Clone for TupleArgumentsFlag

fn clone(&self) -> TupleArgumentsFlag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<TupleArgumentsFlag> for TupleArgumentsFlag

fn eq(&self, other: &TupleArgumentsFlag) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
