Enum ConfigResult

#[repr(u32)]
pub enum ConfigResult {
    Ok = 0,
    EmptyConfig = 1,
    InvalidConfig = 2,
    UnsupportedConfig = 3,
    TooManyDisplays = 4,
    UnsupportedDisplayModes = 5,
}

The result of checking a draft display config.

Values are produced by [fuchsia.hardware.display/Coordinator.CheckConfig].

Variants

Ok = 0

The config is compatible with the current hardware.

EmptyConfig = 1

The config doesn’t impact any connected display.

Said differently, the config does not assign layers to any display that is still connected to the system. A simple but unlikely case is that the client did not assign any layers to any displays. A more complex and likely case is that the client did assign layers to at least one display, but that display is no longer connected to the system.

Clients should process any display changes and retry the [Coordinator.CheckConfig] call.

InvalidConfig = 2

The config is not compatible with any hardware.

UnsupportedConfig = 3

The config layer assignment is not supported by the current hardware.

TooManyDisplays = 4

The config uses more than the number of connected displays.

UnsupportedDisplayModes = 5

The config display modes are not supported by the current hardware.

The client should try a different set of displays or display modes.

Implementations

impl ConfigResult

pub fn from_primitive(prim: u32) -> Option<ConfigResult>

pub const fn into_primitive(self) -> u32

Trait Implementations

impl Clone for ConfigResult

fn clone(&self) -> ConfigResult

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConfigResult

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

Formats the value using the given formatter.

impl<D> Decode<ConfigResult, D> for ConfigResult

where D: ResourceDialect,

fn new_empty() -> ConfigResult

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<(), Error>

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

impl<D> Encode<ConfigResult, D> for ConfigResult

where D: ResourceDialect,

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

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

impl Hash for ConfigResult

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

where __H: Hasher,

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 ConfigResult

fn cmp(&self, other: &ConfigResult) -> 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 ConfigResult

fn eq(&self, other: &ConfigResult) -> 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 ConfigResult

fn partial_cmp(&self, other: &ConfigResult) -> 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 ConfigResult

type Owned = ConfigResult

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 ConfigResult

type Borrowed<'a> = ConfigResult

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: &<ConfigResult as TypeMarker>::Owned, ) -> <ConfigResult as ValueTypeMarker>::Borrowed<'_>

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