Enum PresentError 

#[non_exhaustive]
pub enum PresentError {
    ShortFrame {
        height: u32,
        stride: u32,
        needed: usize,
        got: usize,
    },

    Bind(String),
}

What went wrong presenting a frame.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ShortFrame

The source buffer is shorter than height * stride says it is.

Fields

height: u32

Rows the sink expects.

stride: u32

Bytes per row the caller declared.

needed: usize

Bytes that implies.

got: usize

Bytes actually supplied.

WouldBlock

Every ring slot is busy. Retry once a flip has completed.

Paint(PaintError)

Painting the frame into a slot failed.

Build(SceneError)

The scene could not build this frame.

Commit(CoreError)

A property write or the commit itself was refused.

Bind(String)

Setting the scene up against this output failed.

Trait Implementations

impl Debug for PresentError

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

Formats the value using the given formatter.

impl Display for PresentError

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

Formats the value using the given formatter.

impl Error for PresentError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<CoreError> for PresentError

fn from(source: CoreError) -> Self

Converts to this type from the input type.

impl From<PaintError> for PresentError

fn from(error: PaintError) -> Self

Converts to this type from the input type.

impl From<SceneError> for PresentError

fn from(source: SceneError) -> Self

Converts to this type from the input type.
