Enum Error 

#[non_exhaustive]
pub enum Error {
    FmtError(Error),
    Unimplemented(String),
    #[non_exhaustive]
    GlobalVariablesNotEnabled {
        example: String,
    },
    #[non_exhaustive]
    ResourcesNotEnabled {
        example: String,
    },
}

Errors returned by the Rust-generating backend.

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.

FmtError(Error)

The provided fmt::Write implementation returned an error.

Unimplemented(String)

The Rust backend currently does not support this particular shader functionality.

#[non_exhaustive]

GlobalVariablesNotEnabled

To use a shader with private global variables, Config::global_struct() must be set.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

example: String

The name of one of the prohibited global variables.

#[non_exhaustive]

ResourcesNotEnabled

To use a shader with resources, Config::resource_struct() must be set.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

example: String

The name of one of the prohibited resources.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.
