Trait Implementations

impl AnyCompatible for DLDataType

AnyCompatible implementation for DLDataType

This implementation allows DLDataType to be used with the TVM FFI Any system, enabling type-safe conversion between DLDataType and the generic Any type.

fn type_str() -> String

Get the type string identifier for DLDataType

Returns

The string “DataType” to match the C++ representation

unsafe fn copy_to_any_view(src: &Self, data: &mut TVMFFIAny)

Copy a DLDataType to an Any view

Arguments

• src - The DLDataType to copy from
• data - The Any view to copy to

unsafe fn move_to_any(src: Self, data: &mut TVMFFIAny)

Move a DLDataType into an Any

Arguments

• src - The DLDataType to move from
• data - The Any to move into

unsafe fn check_any_strict(data: &TVMFFIAny) -> bool

Check if an Any contains a DLDataType

Arguments

• data - The Any to check

Returns

true if the Any contains a DLDataType, false otherwise

unsafe fn copy_from_any_view_after_check(data: &TVMFFIAny) -> Self

Copy a DLDataType from an Any view (after type check)

Arguments

• data - The Any view to copy from

Returns

The copied DLDataType

Safety

The caller must ensure that data contains a DLDataType

unsafe fn move_from_any_after_check(data: &mut TVMFFIAny) -> Self

Move a DLDataType from an Any (after type check)

Arguments

• data - The Any to move from

Returns

The moved DLDataType

Safety

The caller must ensure that data contains a DLDataType

unsafe fn try_cast_from_any_view(data: &TVMFFIAny) -> Result<Self, ()>

Try to cast an Any view to a DLDataType

This method supports both direct DLDataType conversion and string parsing.

Arguments

• data - The Any view to cast from

Returns

• Ok(DLDataType) - Successfully cast to DLDataType
• Err(()) - Failed to cast (wrong type or invalid string)

unsafe fn is_undefined(field: *const Self) -> bool

Whether field, which holds a value of this type or all-zero bytes, holds all-zero bytes that are no value of this type, as a null object reference, a string of type index None or a zero device type: a field that a creator left undefined for reflection to set, as C++ UnsafeInit leaves a reference undefined (null). Unlike a C++ undefined reference, it is no value; a nullable reference is Option<T>, whose None is a defined value.

fn get_mismatch_type_info(data: &TVMFFIAny) -> String

Get the type key of a type when TryCastFromAnyView fails.

fn type_schema() -> String

The type schema of the type: the JSON object C++ TypeTraits<T>::TypeSchema writes, which the type schemas of functions and fields embed.

fn to_any(&self) -> Any

Borrow self into an owned Any, increfing object-backed values.

impl<'a> ArgIntoRef for &'a DLDataType

type Target = DLDataType

fn to_ref(&self) -> &Self::Target

impl ArgIntoRef for DLDataType

type Target = DLDataType

fn to_ref(&self) -> &Self::Target

impl Clone for DLDataType

fn clone(&self) -> DLDataType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DLDataTypeExt for DLDataType

fn to_string(&self) -> String

Convert the DLDataType to a string representation

fn try_from_str(dtype_str: &str) -> Result<Self>

Parse a string representation into a DLDataType

impl Debug for DLDataType

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

Formats the value using the given formatter.

impl<'a> IntoArgHolder for &'a DLDataType

type Target = &'a DLDataType

fn into_arg_holder(self) -> Self::Target

impl IntoArgHolder for DLDataType

type Target = DLDataType

fn into_arg_holder(self) -> Self::Target

impl PartialEq for DLDataType

fn eq(&self, other: &DLDataType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<Any> for DLDataType

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: Any) -> Result<Self, Self::Error>

Performs the conversion.

impl<'a> TryFrom<AnyView<'a>> for DLDataType

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: AnyView<'a>) -> Result<Self, Self::Error>

Performs the conversion.
