Enum Error 

#[non_exhaustive]
pub enum Error {
    NoCompatibleDevice,
    WgpuCreateSurfaceError(CreateSurfaceError),
    UnsupportedSurfaceFormat,
    UnavailableBufferUsed(&'static str, &'static str),

}

Errors that can occur in Vello.

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.

NoCompatibleDevice

Available on crate feature wgpu only.

There is no available device with the features required by Vello.

WgpuCreateSurfaceError(CreateSurfaceError)

Available on crate feature wgpu only.

Failed to create surface. See wgpu::CreateSurfaceError for more information.

UnsupportedSurfaceFormat

Available on crate feature wgpu only.

Surface doesn’t support the required texture formats. Make sure that you have a surface which provides one of TextureFormat::Rgba8Unorm or TextureFormat::Bgra8Unorm as texture formats.

UnavailableBufferUsed(&'static str, &'static str)

Available on crate feature wgpu only.

Used a buffer inside a recording while it was not available. Check if you have created it and not freed before its last usage.

BufferAsyncError(BufferAsyncError)

Available on crate feature wgpu only.

Failed to async map a buffer. See wgpu::BufferAsyncError for more information.

DownloadError(&'static str)

Available on crate features debug_layers and wgpu only.

Failed to download an internal buffer for debug visualization.

WgpuErrorFromScope(Error)

Available on crate feature wgpu only.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
