Enum FormatError 

pub enum FormatError {
    Json(Error),
    Io(Error),
    UnknownFormat(String),
    FormatMismatch {
        expected: String,
        actual: String,
    },
}

Errors that can occur during session serialization/deserialization.

Variants

Json(Error)

JSON (de)serialization failure; wraps the underlying serde_json::Error.

Io(Error)

Underlying filesystem I/O failure.

UnknownFormat(String)

The session payload declared a format identifier that this crate does not recognize. Carries the unknown identifier.

FormatMismatch

The session payload’s format identifier did not match the caller’s expectation (e.g. expected JSON, found bincode header).

Fields

expected: String

Format identifier the caller expected to read.

actual: String

Format identifier actually found in the payload.

Trait Implementations

impl Debug for FormatError

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

Formats the value using the given formatter.

impl Display for FormatError

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

Formats the value using the given formatter.

impl Error for FormatError

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.
