Module executorch_sys::torch::executor

Modules

• util

Structs

• ArrayRef
  Represents a constant reference to an array (0 or more elements consecutively in memory), i.e. a start pointer and a length. It allows various APIs to take consecutive elements easily and conveniently.
• BoxedEvalueList
• DataLoader
  Loads from a data source.
• EValue
• EventTracer
  EventTracer is a class that users can inherit and implement to log/serialize/stream etc. the profiling and debugging events that are generated at runtime for a model. An example of this is the ETDump implementation in the SDK codebase that serializes these events to a flatbuffer.
• FreeableBuffer
  A read-only buffer than can be freed.
• HierarchicalAllocator
  A group of buffers that can be used to represent a device’s memory hierarchy.
• MemoryAllocator
  A class that does simple allocation based on a size and returns the pointer to the memory address. It bookmarks a buffer with certain size. The allocation is simply checking space and growing the cur_ pointer with each allocation request.
• MemoryManager
  A container class for allocators used during Method load and execution.
• Method
  An executable method of an executorch program. Maps to a python method like forward() on the original nn.Module.
• MethodMeta
  Describes a a method in an ExecuTorch program.
• Module
  A facade class for loading programs and executing methods within them.
• Program
  A deserialized ExecuTorch program binary.
• Result
  Result type wrapping either a value of type T or an error.
• Span
  Represent a reference to an array (0 or more elements consecutively in memory), i.e. a start pointer and a length. It allows various APIs to take consecutive elements easily and conveniently.
• Tensor
  A minimal Tensor type whose API is a source compatible subset of at::Tensor.
• TensorImpl
  Manages the storage behind an ETensor (torch::executor::Tensor).
• TensorInfo
  Metadata about a specific tensor of an ExecuTorch Program.
• optional
  Leaner optional class, subset of c10, std, and boost optional APIs.
• optional_trivial_init_t

Enums

• Error
  ExecuTorch Error type.
• Module_MlockConfig
  Enum to define memory locking behavior.
• Program_HeaderStatus
  Describes the presence of an ExecuTorch program header.
• Program_Verification
  Types of validation that the Program can do before parsing the data.
• ScalarType
  Data types (dtypes) that can be used as element types in ETensors.
• Tag
• TensorShapeDynamism
  Rank can never change in executorch. But shape sometimes can. This enum is used to help provide better safety in kernels on what tensors are resizable

Constants

• DelegateDebugIdType_kInt
  Indicates a delegate event logged using an integer delegate debug identifier.
• DelegateDebugIdType_kNone
  Default value, indicates that it’s not a delegate event.
• DelegateDebugIdType_kStr
  Indicates a delegate event logged using a string delegate debug identifier i.e. the delegate debug id is a pointer to a string table managed by the class implementing EventTracer functionality.
• HierarchicalAllocator_kSpanArraySize
• LoggedEValueType_kIntermediateOutput
  Intermediate output from an operator.
• LoggedEValueType_kProgramOutput
  Output at the program level. This is essentially the output of the model.
• MemoryAllocator_kDefaultAlignment
  Default alignment of memory returned by this class. Ensures that pointer fields of structs will be aligned. Larger types like long double may not be, however, depending on the toolchain and architecture.
