Enum WGPUPresentMode

#[repr(i32)]
pub enum WGPUPresentMode {
    Undefined = 0,
    Fifo = 1,
    FifoRelaxed = 2,
    Immediate = 3,
    Mailbox = 4,
}

Variants

Undefined = 0

Present mode is not specified. Use the default.

Fifo = 1

The presentation of the image to the user waits for the next vertical blanking period to update in a first-in, first-out manner.

Tearing cannot be observed and frame-loop will be limited to the display’s refresh rate.

This is the only mode that’s always available.

FifoRelaxed = 2

The presentation of the image to the user tries to wait for the next vertical blanking period but may decide to not wait if a frame is presented late.

Tearing can sometimes be observed but late-frame don’t produce a full-frame stutter in the presentation.

This is still a first-in, first-out mechanism so a frame-loop will be limited to the display’s refresh rate.

Immediate = 3

The presentation of the image to the user is updated immediately without waiting for a vertical blank.

Tearing can be observed but latency is minimized.

Mailbox = 4

The presentation of the image to the user waits for the next vertical blanking period to update to the latest provided image.

Tearing cannot be observed and a frame-loop is not limited to the display’s refresh rate.

fn clone(&self) -> WGPUPresentMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WGPUPresentMode

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

Formats the value using the given formatter.

impl Display for WGPUPresentMode

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

Formats the value using the given formatter.

impl<'_derivative_strum> From<&'_derivative_strum WGPUPresentMode> for &'static str

fn from(x: &'_derivative_strum WGPUPresentMode) -> &'static str

Converts to this type from the input type.

impl From<WGPUPresentMode> for &'static str

fn from(x: WGPUPresentMode) -> &'static str

Converts to this type from the input type.

impl FromStr for WGPUPresentMode

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<WGPUPresentMode, <Self as FromStr>::Err>

Parses a string s to return a value of this type.
