Variants

Eof

End of input reached unexpectedly

TypeNotFound(u32)

Type ID not found in registry

InvalidVariant(u8)

Variant index not found

InvalidUtf8

Invalid UTF-8 in string data

InvalidChar(u32)

Invalid unicode codepoint

BadInput(String)

Bad input data

BadType(String)

Unsupported type for operation

Ser(String)

Serialization/deserialization error

NotSupported(&'static str, String)

Serializing from type to target not supported

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 Error for Error

fn custom<T: Display>(msg: T) -> Self

Used when a Serialize implementation encounters any error while serializing a type.

impl From<Error> for Error

fn from(_: Error) -> Self

Converts to this type from the input type.
