GLSL conversion error.

Such an errors can happen when a module is ill-formed.

Variants

NoVertexShader

No vertex shader was found. A vertex shader is required in order to build a shading pipeline.

NoFragmentShader

No fragment shader was found. A fragment shader is required in order to build a shading pipeline.

OutputHasMainQualifier

The output must not have a qualifier.

ReturnTypeMustBeAStruct(TypeSpecifier)

The returned value must not be a struct.

WrongOutputFirstField(StructFieldSpecifier)

The first field has the wrong type.

OutputFieldCannotBeStruct(usize, StructSpecifier)

The field of a type used as output cannot be a struct.

This variant also gives the index of the field.

OutputFieldCannotBeTypeName(usize, TypeName)

The field of a type used as output cannot be a type name.

This variant also gives the index of the field.

OutputFieldCannotHaveSeveralIdentifiers(usize, StructFieldSpecifier)

The field of a type used as output cannot have several identifiers (only one).

This variant also gives the index of the field.

UnknownInputType(TypeName)

The input type is unknown.

WrongNumberOfArgs(ExpectedNumberOfArgs, FoundNumberOfArgs)

Wrong number of arguments.

NotTypeName

The type is not a required type name.

WrongGeometryInput

The geometry input is wrong.

WrongGeometryInputDim(usize)

The geometry input’s dimension is wrong.

WrongGeometryOutputLayout(Option<TypeQualifier>)

The geometry output layout is wrong.

Trait Implementations

impl Clone for GLSLConversionError

fn clone(&self) -> GLSLConversionError
