Enum ListError 

#[non_exhaustive]
pub enum ListError {
    NotFound,
    PermissionDenied,
    AuthRequired(SharedString),
    Disconnected(SharedString),
    Other(SharedString),
}

Why a source could not list a directory. The picker shows the message and, for a failure that waiting can fix, an action: Retry for a lost connection or an error, and “Sign in” for a source that needs the user to log in, which calls the application’s own handler.

A source returns one from list for any failure. An io::Error converts into the matching variant.

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 directory does not exist.

PermissionDenied

The user may not list the directory.

AuthRequired(SharedString)

The source needs the user to sign in. The text says why, and is shown to the user.

Disconnected(SharedString)

The connection to the source was lost. The text says what happened, and is shown to the user.

Other(SharedString)

Any other failure. The text is shown to the user.

Implementations

impl ListError

pub fn message(&self) -> SharedString

The text the picker shows.

pub fn is_retryable(&self) -> bool

Whether asking again can succeed, which gives the list a Retry action.

pub fn needs_sign_in(&self) -> bool

Whether the user must sign in, which gives the list a “Sign in” action.
