Struct PyAlloc 

pub struct PyAlloc {
    pub inner: Option<Box<dyn Alloc + Sync + Send>>,
    pub bootstrap_command: Option<BootstrapCommand>,
}

A python class that wraps a Rust Alloc trait object. It represents what is shown on the python side. Internals are not exposed. It ensures that the Alloc is only used once (i.e. moved) in rust.

Fields

inner: Option<Box<dyn Alloc + Sync + Send>>

bootstrap_command: Option<BootstrapCommand>

Implementations

impl PyAlloc

pub fn new( inner: Box<dyn Alloc + Sync + Send>, bootstrap_command: Option<BootstrapCommand>, ) -> Self

Create a new PyAlloc with provided boxed trait.

pub fn take(&mut self) -> Option<Box<dyn Alloc + Sync + Send>>

Take the internal Alloc object.

impl PyAlloc

pub fn reshape( &mut self, shape: &Bound<'_, PyDict>, ) -> PyResult<Option<PyAlloc>>

Trait Implementations

impl<'py> IntoPyObject<'py> for PyAlloc

type Target = PyAlloc

The Python output type

type Output = Bound<'py, <PyAlloc as IntoPyObject<'py>>::Target>

The smart pointer type to use.

type Error = PyErr

The type returned in the event of a conversion error.

fn into_pyobject( self, py: Python<'py>, ) -> Result<<Self as IntoPyObject<'_>>::Output, <Self as IntoPyObject<'_>>::Error>

Performs the conversion.

impl PyClass for PyAlloc

type Frozen = False

Whether the pyclass is frozen.

const RAW_DOC: &'static CStr = /// A python class that wraps a Rust Alloc trait object. It represents what /// is shown on the python side. Internals are not exposed. /// It ensures that the Alloc is only used once (i.e. moved) in rust.

Docstring for the class provided on the struct or enum.

const DOC: &'static CStr

Fully rendered class doc, including the text_signature if a constructor is defined.

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<PyAlloc>

This handles following two situations:

type Inventory = Pyo3MethodsInventoryForPyAlloc

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.

impl PyTypeInfo for PyAlloc

const NAME: &'static str = "Alloc"

Class name.

fn type_object_raw(py: Python<'_>) -> *mut PyTypeObject

Returns the PyTypeObject instance for this type.

fn type_object(py: Python<'_>) -> Bound<'_, PyType>

Returns the safe abstraction over the type object.

fn is_type_of(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type or a subclass of this type.

fn is_exact_type_of(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type.
