Enum TransferError 

pub enum TransferError {
    Io(Error),
    Json(Error),
    Base64(DecodeError),
    UnsupportedVersion(u32),
    Storage(Error),
    Conflict(String),
}

Errors that can occur during export or import operations.

Variants

Io(Error)

Underlying I/O failure (file create, write, etc.).

Json(Error)

JSON serialization or deserialization failure.

Base64(DecodeError)

A message payload could not be decoded from base64.

UnsupportedVersion(u32)

The export document declares a format version this build cannot handle.

Storage(Error)

A storage operation failed during export or import.

Conflict(String)

A stream in the import already exists and the conflict policy forbids it.

Trait Implementations

impl Debug for TransferError

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

Formats the value using the given formatter.

impl Display for TransferError

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

Formats the value using the given formatter.

impl Error for TransferError

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.
