Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Io

File-system failure.

Fields

path: PathBuf

Affected path.

source: Error

Underlying error.

Json

A line could not be (de)serialised.

Fields

path: PathBuf

Affected path (empty for in-memory data).

line: usize

1-based line number (0 when not line based).

source: Error

Underlying error.

InvalidSessionId(String)

Session id failed validation (message text is fixed, verbatim).

UnknownEntry(EntryId)

Entry id not present.

AmbiguousId(Vec<PathBuf>)

Session id prefix matched several files.

UnsupportedVersion(u32)

File written by a newer session format.

MissingHeader(PathBuf)

The file has content but no valid header line.

MissingCwd(PathBuf)

The header has no cwd and no override was supplied.

InvalidAppend(&'static str)

The append is not allowed (reason given).

NotFound(PathBuf)

Required file does not exist.

Cancelled

Listing was cancelled through the cancel flag.

Trait Implementations

impl Debug for SessionError

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

Formats the value using the given formatter.

impl Display for SessionError

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

Formats the value using the given formatter.

impl Error for SessionError

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.
