Enum Error 

pub enum Error {
    AlreadyExists(PathBuf),
    NotFound(PathBuf),
    ProtocolMismatch {
        found: u32,
        expected: u32,
    },
    Io(Error),
    Serde(Error),
}

Errors from the file adapter itself.

Distinct from Response::Error: that is the game rejecting a request (illegal action); these are the file misbehaving (missing, already exists, unreadable, wrong protocol version).

Variants

AlreadyExists(PathBuf)

FileSession::create was asked to write where a file already exists.

NotFound(PathBuf)

FileSession::handle was asked to load a path with no file.

ProtocolMismatch

The save was written by an incompatible PROTOCOL_VERSION.

Fields

found: u32

The version stamped in the save file.

expected: u32

The version this build understands.

Io(Error)

Reading or writing the save file failed.

Serde(Error)

The save file did not parse, or a state failed to serialize.

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.
