Enum luminance::shader::ProgramError

#[non_exhaustive]pub enum ProgramError {
    CreationFailed(String),
    StageError(StageError),
    LinkFailed(String),
    Warning(ProgramWarning),
}

Errors that a Program can generate.

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.

CreationFailed(String)

Creating the program failed.

StageError(StageError)

A shader stage failed to compile or validate its state.

LinkFailed(String)

Program link failed. You can inspect the reason by looking at the contained String.

Warning(ProgramWarning)

A program warning.

Implementations

impl ProgramError

pub fn creation_failed(reason: impl Into<String>) -> Self

Creating the program failed.

pub fn stage_error(e: StageError) -> Self

A shader stage failed to compile or validate its state.

pub fn link_failed(reason: impl Into<String>) -> Self

Program link failed. You can inspect the reason by looking at the contained String.

pub fn warning(w: ProgramWarning) -> Self

A program warning.

Trait Implementations

impl Debug for ProgramError

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

Formats the value using the given formatter.

impl Display for ProgramError

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

Formats the value using the given formatter.

impl Error for ProgramError

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<ProgramWarning> for ProgramError

fn from(e: ProgramWarning) -> Self

Performs the conversion.

impl From<StageError> for ProgramError

fn from(e: StageError) -> Self

Performs the conversion.
