Struct rustpython_vm::function::Args

pub struct Args<T = PyObjectRef>(_);

A list of positional argument values.

A built-in function with a Args parameter is analogous to a Python function with *args. All remaining positional arguments are extracted (and hence the function will permit an arbitrary number of them).

Args optionally accepts a generic type parameter to allow type checks or conversions of each argument.

Methods

impl<T> Args<T>

pub fn into_vec(self) -> Vec<T>

impl<T: PyValue> Args<PyRef<T>>

pub fn into_tuple(self, vm: &VirtualMachine) -> PyObjectRef

Trait Implementations

impl<T: Clone> Clone for Args<T>

fn clone(&self) -> Args<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> FromArgs for Args<T> where
    T: TryFromObject, 

fn from_args(
    vm: &VirtualMachine,
    args: &mut PyFuncArgs
) -> Result<Self, ArgumentError>

Extracts this item from the next argument(s).

fn arity() -> RangeInclusive<usize>

The range of positional arguments permitted by the function signature.

impl<T> IntoIterator for Args<T>

type Item = T

The type of the elements being iterated over.

type IntoIter = IntoIter<T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
