Enum luminance::shader::UniformWarning

#[non_exhaustive]pub enum UniformWarning {
    Inactive(String),
    TypeMismatch(String, UniformType),
    UnsupportedType(String, UniformType),
}

Warnings related to uniform issues.

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.

Inactive(String)

Inactive uniform (not in use / no participation to the final output in shaders).

TypeMismatch(String, UniformType)

Type mismatch between the static requested type (i.e. the T in Uniform<T> for instance) and the type that got reflected from the backend in the shaders.

The String is the name of the uniform; the second one gives the type mismatch.

UnsupportedType(String, UniformType)

The requested type is unsupported by the backend.

The String is the name of the uniform. The UniformType is the type that is not supported by the backend.

Implementations

impl UniformWarning

pub fn inactive<N>(name: N) -> Self where
    N: Into<String>, 

Create an inactive uniform warning.

pub fn type_mismatch<N>(name: N, ty: UniformType) -> Self where
    N: Into<String>, 

Create a type mismatch.

pub fn unsupported_type<N>(name: N, ty: UniformType) -> Self where
    N: Into<String>, 

Create an unsupported type error.

Trait Implementations

impl Debug for UniformWarning

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

Formats the value using the given formatter.

impl Display for UniformWarning

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

Formats the value using the given formatter.

impl Error for UniformWarning

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<UniformWarning> for ProgramWarning

fn from(e: UniformWarning) -> Self

Performs the conversion.
