Enum Error 

pub enum Error {
    Io(Error),
    Value(String),
}

An error that occurred during serialization.

Variants

Io(Error)

An error from the underlying writer.

Value(String)

A value cannot be represented in CBOR.

Contains a description of the problem. Without the alloc feature only a static description can be carried, so the messages that serde composes at runtime are reduced to a generic one.

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 StdError + '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<U: Display>(msg: U) -> Self

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

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

Available on crate feature alloc only.

fn from(value: Error) -> Self

Converts to this type from the input type.
