Enum QueryId

pub enum QueryId {
    VendorId,
    DeviceId,
    VendorVersion,
    IsTotalTimeSupported,
    MaximumInflightParams,
    MagmaQueryTotalTime,
    VendorQuery0,
    // some variants omitted
}

Types of information about the hardware and driver that can be queried from the Magma system driver. Vendor-specific ID numbers may be used, but those IDs will be listed elsewhere.

Variants

VendorId

Returns the hardware vendor ID (simple result) - should be the PCI ID of the hardware vendor if possible, or the Khronos vendor ID otherwise.

DeviceId

Returns the hardware device ID (simple result)

VendorVersion

Returns the version of the vendor interfaces supported by the system driver.

IsTotalTimeSupported

Returns true if MAGMA_QUERY_TOTAL_TIME is supported (simple result)

MaximumInflightParams

Upper 32bits: max inflight messages, lower 32bits: max inflight memory (MB) (simple result)

MagmaQueryTotalTime

Returns a struct magma_total_time_query_result (buffer result); see: src/graphics/lib/magma/include/magma/magma_common_defs.h

Implementations

impl QueryId

pub fn from_primitive(prim: u64) -> Option<Self>

pub fn from_primitive_allow_unknown(prim: u64) -> Self

pub fn unknown() -> Self

Trait Implementations

impl Clone for QueryId

fn clone(&self) -> QueryId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QueryId

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<QueryId, D> for QueryId

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<()>

Decodes an object of type T from the decoder’s buffers into self.

impl<D: ResourceDialect> Encode<QueryId, D> for QueryId

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl Hash for QueryId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for QueryId

fn cmp(&self, other: &QueryId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for QueryId

fn eq(&self, other: &QueryId) -> 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 PartialOrd for QueryId

fn partial_cmp(&self, other: &QueryId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TypeMarker for QueryId

type Owned = QueryId

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for QueryId

type Borrowed<'a> = QueryId

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow(value: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
