Struct LogState 

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

A log state for capturing GPU shader logs.

C++ equivalent: MTL::LogState

Log states are created from a device using a descriptor. They can be attached to command buffers to capture shader logs.

Implementations

impl LogState

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

Create from a raw pointer.

Safety

The pointer must be a valid Metal log state.

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

Get the raw pointer.

pub unsafe fn add_log_handler_raw(&self, block: *const c_void)

Add a log handler (raw block pointer version).

C++ equivalent: void addLogHandler(void(^)(NS::String*, NS::String*, LogLevel, NS::String*))

Safety

The block pointer must be a valid Objective-C block.

pub fn add_log_handler<F>(&self, handler: F)

where F: Fn(&str, &str, LogLevel, &str) + Send + 'static,

Add a log handler to receive shader log messages.

C++ equivalent: void addLogHandler(void(^)(NS::String*, NS::String*, LogLevel, NS::String*))

The handler is called with:

• subsystem - The subsystem that generated the log
• category - The category of the log message
• level - The severity level of the log message
• message - The actual log message content

Trait Implementations

impl Clone for LogState

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 LogState

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

Formats the value using the given formatter.

impl Drop for LogState

fn drop(&mut self)

Executes the destructor for this type.

impl Referencing for LogState

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.

fn release(&self)

Release the object, decrementing its reference count.

fn autorelease(&self) -> Self

where Self: Clone,

Autorelease the object.

fn retain_count(&self) -> usize

Get the retain count of the object.
