Enum FileError

Why an operation on a PickedFile did not happen.

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

The file is not there any more, or, in a browser, its handle was let go of or belongs to a page that has since been reloaded.

PermissionDenied

The platform or the user refused access.

ReadOnly

The file can only be read: an upload, or one the platform will not let this run write.

NotAFolder

A listing or a child was asked of a file.

IsAFolder

A read or a write was asked of a folder.

TooLarge

The file is longer than one read may carry. Nothing was read. len is its length when it is known, and limit + 1 when all that is known is that it is longer.

Fields

len: u64

limit: u64

Unavailable(String)

This run has no way to do it. The reason is in the text.

Io(String)

Any other failure, as the platform described it.

Trait Implementations

impl Clone for FileError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileError

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

Formats the value using the given formatter.

impl Display for FileError

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

Formats the value using the given formatter.

impl Eq for FileError

impl Error for FileError

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 PartialEq for FileError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
