Enum ErrorSource

#[non_exhaustive]
pub enum ErrorSource {
    IoError(Arc<Error>),
    Inaccessible(Error),
    Permissions(Error),
    NoLock,
    Serde(Arc<Error>),
    AlreadyLocked,
    Bug(Bug),
}

An underlying error manipulating persistent state.

Since these are more or less orthogonal to what we were doing and where the problem was, this is a separate type.

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.

IoError(Arc<Error>)

An IO error occurred.

Inaccessible(Error)

Inaccessible path, or permissions were incorrect

Permissions(Error)

👎Deprecated: use ErrorSource::Inaccessible instead

Inaccessible path, or permissions were incorrect

This variant name is misleading - see the docs for fs_mistrust::Error. Please use ErrorSource::Inaccessible instead.

NoLock

Tried to save without holding an exclusive lock.

Serde(Arc<Error>)

Problem when serializing or deserializing JSON data.

AlreadyLocked

Another task or process holds this persistent state lock, but we need exclusive access

Trait Implementations

impl Clone for ErrorSource

fn clone(&self) -> ErrorSource

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ErrorSource

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

Formats the value using the given formatter.

impl Display for ErrorSource

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

Formats the value using the given formatter.

impl Error for ErrorSource

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
