Struct FunctionConstantValues 

pub struct FunctionConstantValues(/* private fields */);

Constant values for specializing a function.

C++ equivalent: MTL::FunctionConstantValues

Function constant values allow you to specialize a function at runtime by providing values for function constants defined in shader code.

Implementations

impl FunctionConstantValues

pub fn alloc() -> Option<Self>

Allocate a new function constant values object.

C++ equivalent: static FunctionConstantValues* alloc()

pub fn init(&self) -> Option<Self>

Initialize an allocated function constant values object.

C++ equivalent: FunctionConstantValues* init()

pub fn new() -> Option<Self>

Create a new function constant values object.

pub unsafe fn from_raw(ptr: *mut c_void) -> Option<Self>

Create from a raw pointer.

Safety

The pointer must be a valid Metal function constant values object.

pub fn as_raw(&self) -> *mut c_void

Get the raw pointer.

pub fn reset(&self)

Reset all constant values.

C++ equivalent: void reset()

pub unsafe fn set_constant_value_at_index( &self, value: *const c_void, data_type: DataType, index: UInteger, )

Set a constant value by index.

C++ equivalent: void setConstantValue(const void*, DataType, NS::UInteger)

Safety

The value pointer must be valid and point to data of the correct type.

pub unsafe fn set_constant_value_with_name( &self, value: *const c_void, data_type: DataType, name: &str, )

Set a constant value by name.

C++ equivalent: void setConstantValue(const void*, DataType, const NS::String*)

Safety

The value pointer must be valid and point to data of the correct type.

pub unsafe fn set_constant_values( &self, values: *const c_void, data_type: DataType, location: UInteger, length: UInteger, )

Set multiple constant values in a range.

C++ equivalent: void setConstantValues(const void*, DataType, NS::Range)

Safety

The values pointer must be valid and point to an array of data of the correct type.

pub fn set_bool_at_index(&self, value: bool, index: UInteger)

Set a boolean constant value by index.

pub fn set_int_at_index(&self, value: i32, index: UInteger)

Set an integer constant value by index.

pub fn set_uint_at_index(&self, value: u32, index: UInteger)

Set an unsigned integer constant value by index.

pub fn set_float_at_index(&self, value: f32, index: UInteger)

Set a float constant value by index.

Trait Implementations

impl Clone for FunctionConstantValues

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionConstantValues

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

Formats the value using the given formatter.

impl Default for FunctionConstantValues

fn default() -> Self

Returns the “default value” for a type.

impl Drop for FunctionConstantValues

fn drop(&mut self)

impl Referencing for FunctionConstantValues

fn as_ptr(&self) -> *const c_void

Get the raw pointer to the Objective-C object.

fn as_mut_ptr(&self) -> *mut c_void

Get the raw mutable pointer to the Objective-C object.

fn retain(&self) -> Self

where Self: Clone,

Retain the object, incrementing its reference count.
