Struct dlpackrs::ffi::DLManagedTensor

#[repr(C)]
pub struct DLManagedTensor {
    pub dl_tensor: DLTensor,
    pub manager_ctx: *mut c_void,
    pub deleter: Option<unsafe extern "C" fn(*mut DLManagedTensor)>,
}

\brief C Tensor object, manage memory of DLTensor. This data structure is intended to facilitate the borrowing of DLTensor by another framework. It is not meant to transfer the tensor. When the borrowing framework doesn’t need the tensor, it should call the deleter to notify the host that the resource is no longer needed.

Fields

dl_tensor: DLTensor

\brief DLTensor which is being memory managed

manager_ctx: *mut c_void

\brief the context of the original host framework of DLManagedTensor in which DLManagedTensor is used in the framework. It can also be NULL.

deleter: Option<unsafe extern "C" fn(*mut DLManagedTensor)>

\brief Destructor signature void ()(void) - this should be called to destruct manager_ctx which holds the DLManagedTensor. It can be NULL if there is no way for the caller to provide a reasonable destructor. The destructors deletes the argument self as well.

Trait Implementations

impl Clone for DLManagedTensor

fn clone(&self) -> DLManagedTensor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DLManagedTensor

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for DLManagedTensor

fn default() -> DLManagedTensor

Returns the “default value” for a type.

impl<'tensor, C> From<DLManagedTensor> for ManagedTensor<'tensor, C>

fn from(dlm: DLManagedTensor) -> Self

Converts to this type from the input type.

impl<C> From<DLManagedTensor> for ManagedTensorProxy<C>

fn from(dlmt: DLManagedTensor) -> Self

Converts to this type from the input type.

impl<'tensor, C> From<ManagedTensor<'tensor, C>> for DLManagedTensor

fn from(mt: ManagedTensor<'tensor, C>) -> Self

Converts to this type from the input type.

impl<C> From<ManagedTensorProxy<C>> for DLManagedTensor

fn from(pmt: ManagedTensorProxy<C>) -> Self

Converts to this type from the input type.

impl<C> From<Pin<&mut ManagedTensorProxy<C>>> for DLManagedTensor

fn from(pmt: Pin<&mut ManagedTensorProxy<C>>) -> Self

Converts to this type from the input type.

impl PartialEq<DLManagedTensor> for DLManagedTensor

fn eq(&self, other: &DLManagedTensor) -> 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.
