    EnvError(String),
    InterfaceError(String),
    ModelError(String),

Error

top level error should handle all sub-errors, but not expose the child candid types

Variants

AuthError(String)

ConfigError(String)

CustomError(String)

EnvError(String)

InterfaceError(String)

ModelError(String)

OpsError(String)

SerializeError(String)

TestError(String)

Test Error as we don’t want to import dev-dependencies

CallError(String)

Common IC errors

CallError : should be automatic with ? CallFailed : use this for wrapping <T, String> return values CandidError : for decode_one errors etc. automatic CandidDecodeFailed : automatic for calls like ::candid()

CallFailed(String)

CandidError(String)

CandidDecodeFailed(String)

Implementations

impl Error

pub fn custom<S: Into<String>>(s: S) -> Self

Build a custom error from a string without defining a new variant.

pub fn test<S: Into<String>>(s: S) -> Self

Build a test error to avoid extra dev-only dependencies.

Trait Implementations

impl CandidType for Error

fn _ty() -> Type

fn id() -> TypeId

fn idl_serialize<__S>(&self, __serializer: __S) -> Result<(), __S::Error>

impl Debug for Error

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

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
