Error returned when the Codegen cannot generate the runtime API.

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.

Decode(Error)

Cannot decode the metadata bytes.

InvalidModule(Span)

Out of line modules are not supported.

InvalidTypePath(String, Error)

Invalid type path.

MissingConstantMetadata(String, String)

Metadata for constant could not be found.

MissingStorageMetadata(String, String)

Metadata for storage could not be found.

MissingCallMetadata(String, String)

Metadata for call could not be found.

MissingRuntimeApiMetadata(String, String)

Metadata for call could not be found.

InvalidCallVariant(u32)

Call variant must have all named fields.

InvalidType(String)

Type should be an variant/enum.

MissingCallType

Extrinsic call type could not be found.

InvalidStorageHasherCount

There are too many or too few hashers.

Fields

storage_entry_name: String

The name of the storage entry

key_count: usize

Number of keys

hasher_count: usize

Number of hashers

TypeGeneration(TypegenError)

Cannot generate types.

Wasm(String)

Error when generating metadata from Wasm-runtime

Other(String)

Other error.

Implementations

impl CodegenError

pub fn into_compile_error(self) -> TokenStream2

Render the error as an invocation of syn::compile_error!.

Trait Implementations

impl Debug for CodegenError

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

Formats the value using the given formatter.

impl Display for CodegenError

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

Formats the value using the given formatter.

impl Error for CodegenError

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 CodegenError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<TypegenError> for CodegenError

fn from(source: TypegenError) -> Self

Converts to this type from the input type.
