Struct tvm::function::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

pub 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
