Enum PickerError 

#[non_exhaustive]
pub enum PickerError {
    Platform {
        message: String,
    },
    Unsupported {
        operation: String,
    },
    Internal {
        message: String,
    },
}

Errors that can occur when presenting a file-picker dialog.

Note that the user cancelling the dialog is not an error — it is represented as Ok(None) on the single-file methods and Ok(vec![]) on multi-file methods.

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.

Platform

The platform returned an error from the native file-picker API.

Fields

message: String

Human-readable description of the platform error.

Unsupported

The current platform does not support the requested operation.

Fields

operation: String

Description of the unsupported operation.

Internal

An internal synchronisation error occurred (e.g. a poisoned mutex).

Fields

Human-readable description of the internal error.

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
