Enum SourceError 

pub enum SourceError<'a> {
    TemplateWgsl {
        uninstantiated_source: &'a Source,
    },
    TemplateNotFound {
        template_name: String,
        mangled_type_args: Vec<String>,
        available_templates: Vec<String>,
    },
    AmbiguousTemplate {
        template_name: String,
        mangled_type_args: Vec<String>,
        matching_source_names: Vec<String>,
        available_templates: Vec<String>,
    },
}

Errors that Source::wgsl_source can produce.

The lifetime parameter 'a is the borrow of the source that triggered the error. A template Source is typically a &'static Source (it lives in static storage, emitted by the macro), so the error is usually SourceError<'static>. The lifetime parameter is present so the error can borrow from &self of a non-static source if needed.

Variants

TemplateWgsl

The source is a template (unresolved module-level type parameters); the caller must use the macro-emitted instantiate::<…>() to obtain a concrete crate::ir::Module first, then call crate::ir::Module::wgsl_source on that.

Fields

uninstantiated_source: &'a Source

The uninstantiated source that triggered the error.

TemplateNotFound

No candidate source declares a template with the requested name. This is a configuration error in the source graph (e.g. a missing wgsl! module import), not a runtime data error.

Fields

template_name: String

mangled_type_args: Vec<String>

available_templates: Vec<String>

AmbiguousTemplate

More than one candidate source declares a template with the requested name, so the instantiation is ambiguous. Disambiguate by removing one of the matching sources from the import graph.

Fields

template_name: String

mangled_type_args: Vec<String>

matching_source_names: Vec<String>

available_templates: Vec<String>

Trait Implementations

impl<'a> Debug for SourceError<'a>

impl<'a> Error for SourceError<'a>

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<SourceError<'_>> for Error

fn from(err: SourceError<'_>) -> Self

Converts to this type from the input type.
