Struct Op

#[repr(C)]
pub struct Op { /* private fields */ }

An operator obtained through Op::get, not a fresh allocation.

Implementations

impl Op

pub fn get(name: &str) -> Result<Self>

The registered operator name, a registry singleton (ir.GetOp).

pub fn has_attr_map(name: &str) -> Result<bool>

Whether any operator registered the attribute name, as Op::HasAttrMap (ir.ListOpAttrNames).

pub fn attr_map<T: AnyCompatible>(name: &str) -> Result<Option<OpAttrMap<T>>>

The live attribute column name, as Op::GetAttrMap<T>, or None when no operator registered it (ir.GetOpAttrColumn).

pub fn list_op_names() -> Result<Array<String>>

The names of the registered operators (ir.ListOpNames).

pub fn list_attr_names() -> Result<Array<String>>

The names of the attributes any operator registered (ir.ListOpAttrNames).

pub fn register(name: &str, doc: &str) -> Result<()>

Register a new operator name with the documentation doc; fails if name is already registered (ir.RegisterOp).

Methods from Deref<Target = OpObj>

pub fn attrs_type_index(&self) -> u32

Runtime type index corresponding to attrs_type_key (not reflected natively).

pub fn validator(&self) -> &Any

Process-local validation callback (not reflected natively): a native function address held as an opaque pointer, a packed function, or None when there is none.

pub fn validator_is_custom(&self) -> bool

Whether the validator was explicitly registered rather than generated (not reflected natively).

Trait Implementations

impl AnyCompatible for Op

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 type_str() -> String

the type string of the type

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

the value to copy to TVMFFIAny

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

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

Copy value from TVMFFIAny after checking caller must ensure that the value is compatible with the type

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

consume the value to move to Any

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

the value to move from TVMFFIAny NOTE: pay very careful attention to avoid memory leak!

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

try to cast the value from AnyView

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 Clone for Op

unsafe fn from_data(data: ObjectArc<Self::ContainerType>) -> Self

Construct a reference view from an owning container handle.

fn same_as<Other>(&self, other: &Other) -> bool

where Other: ObjectRefCore,

Return whether two object references point to the same allocation.

fn downcast_ref<T>(&self) -> Option<&T>

where T: ObjectCore,

Borrow the underlying object as T when its runtime type is T or a subtype.

impl TryFrom<Any> for Op

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.
