Struct rustpython_vm::function::PosArgs

pub struct PosArgs<T = PyObjectRef>(_);

A list of positional argument values.

A built-in function with a PosArgs 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).

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

Implementations

impl<T> PosArgs<T>

pub fn new(args: Vec<T>) -> Self

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

pub fn iter(&self) -> Iter<'_, T>

impl<T: PyPayload> PosArgs<PyRef<T>>

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

Trait Implementations

impl<T> AsRef<[T]> for PosArgs<T>

fn as_ref(&self) -> &[T]

Converts this type into a shared reference of the (usually inferred) input type.

impl<T: Clone> Clone for PosArgs<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<()> for PosArgs<PyObjectRef>

fn from(_args: ()) -> Self

Converts to this type from the input type.

impl<T> From<Vec<T, Global>> for PosArgs<T>

fn from(v: Vec<T>) -> Self

Converts to this type from the input type.

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

fn from_args( vm: &VirtualMachine, args: &mut FuncArgs ) -> 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 PosArgs<T>

type Item = T

The type of the elements being iterated over.

type IntoIter = IntoIter<T, Global>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<T> Traverse for PosArgs<T>where T: Traverse,

fn traverse(&self, tracer_fn: &mut TraverseFn<'_>)

impl traverse() with caution! Following those guideline so traverse doesn’t cause memory error!:
