Enum luminance_front::shader::StageError

#[non_exhaustive]pub enum StageError {
    CompilationFailed(StageType, String),
    UnsupportedType(StageType),
}

Errors that shader stages can emit.

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.

CompilationFailed(StageType, String)

Occurs when a shader fails to compile.

UnsupportedType(StageType)

Occurs when you try to create a shader which type is not supported on the current hardware.

Implementations

impl StageError

pub fn compilation_failed(
    ty: StageType,
    reason: impl Into<String>
) -> StageError

Occurs when a shader fails to compile.

pub fn unsupported_type(ty: StageType) -> StageError

Occurs when you try to create a shader which type is not supported on the current hardware.

Trait Implementations

impl Clone for StageError

fn clone(&self) -> StageError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StageError

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

Formats the value using the given formatter.

impl Display for StageError

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

Formats the value using the given formatter.

impl Error for StageError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<StageError> for ProgramError

fn from(e: StageError) -> ProgramError

Performs the conversion.
