Set of possible renderer errors.

Variants

ShaderCompilationFailed

Compilation of a shader has failed.

Fields

shader_name: String

Name of shader.

error_message: String

Compilation error message.

ShaderLinkingFailed

Means that shader link stage failed, exact reason is inside error_message

Fields

shader_name: String

Name of shader.

error_message: String

Linking error message.

FaultyShaderSource

Shader source contains invalid characters.

UnableToFindShaderUniform(String)

There is no such shader uniform (could be optimized out).

UnableToFindShaderUniformBlock(String)

There is no such shader uniform block.

InvalidTextureData

Texture has invalid data - insufficient size.

Fields

expected_data_size: usize

Expected data size in bytes.

actual_data_size: usize

Actual data size in bytes.

EmptyTextureData

None variant was passed as texture data, but engine does not support it.

InvalidElementRange

Means that you tried to draw element range from GeometryBuffer that does not have enough elements.

Fields

start: usize

First index.

end: usize

Last index.

total: usize

Total amount of triangles.

InvalidAttributeDescriptor

Means that attribute descriptor tries to define an attribute that does not exists in vertex, or it does not match size. For example you have vertex: pos: float2, normal: float3 But you described second attribute as Float4, then you’ll get this error.

InvalidFrameBuffer

Framebuffer is invalid.

FailedToConstructFBO

OpenGL failed to construct framebuffer.

Custom(String)

Custom error. Usually used for internal errors.

GraphicsServerUnavailable

Graphics server disconnected.

Trait Implementations

impl Debug for FrameworkError

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

Formats the value using the given formatter.

impl Display for FrameworkError

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

Formats the value using the given formatter.

impl Error for FrameworkError

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<Box<dyn Error>> for FrameworkError

fn from(e: Box<dyn Error>) -> Self

Converts to this type from the input type.

impl From<NulError> for FrameworkError

fn from(_: NulError) -> Self

Converts to this type from the input type.

impl From<String> for FrameworkError

fn from(v: String) -> Self

Converts to this type from the input type.
