Expand description

The types of error that can occur in a Tetra game.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

PlatformError(String)

Returned when the underlying platform returns an unexpected error. This usually isn’t something your game can reasonably be expected to recover from.

§

FailedToLoadAsset

Returned when your game fails to load an asset. This is usually caused by an incorrect file path, or some form of permission issues.

Fields

§reason: Error

The underlying reason for the error.

§path: PathBuf

The path to the asset that failed to load.

§

InvalidColor

Returned when a color is invalid.

§

InvalidTexture(ImageError)

Returned when a texture’s data is invalid.

§

InvalidShader(String)

Returned when a shader fails to compile.

§

InvalidFont

Returned when a font could not be read.

§

InvalidSound(DecoderError)

Returned when a sound cannot be decoded.

§

NotEnoughData

Returned when not enough data is provided to fill a buffer. This may happen if you’re creating a texture from raw data and you don’t provide enough data.

Fields

§expected: usize

The number of bytes that were expected.

§actual: usize

The number of bytes that were provided.

§

NoAudioDevice

Returned when trying to play back audio without an available device.

§

FailedToChangeDisplayMode(String)

Returned when your game tried to change the display settings (e.g. fullscreen, vsync) but was unable to do so.

§

TessellationError(TessellationError)

Returned when a shape cannot be tessellated.
