Enum FsError 

#[non_exhaustive]
pub enum FsError {
    NotFound(String),
    Other(String),
}

Error returned by a SessionFsProvider method.

The SDK maps this onto the wire schema’s SessionFsError: FsError::NotFound becomes ENOENT, everything else becomes UNKNOWN.

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.

NotFound(String)

File or directory does not exist.

Other(String)

Any other filesystem error (permission denied, I/O error, etc.).

The wire mapping always uses UNKNOWN as the code; the message is preserved for diagnostics.

Trait Implementations

impl Clone for FsError

fn clone(&self) -> FsError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FsError

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

Formats the value using the given formatter.

impl Display for FsError

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

Formats the value using the given formatter.

impl Error for FsError

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.

impl From<Error> for FsError

fn from(err: Error) -> Self

Converts to this type from the input type.
