Enum DirectoryMoveAllowedStrategies 

pub enum DirectoryMoveAllowedStrategies {
    OnlyRename,
    OnlyCopyAndDelete {
        options: DirectoryMoveByCopyOptions,
    },
    Either {
        copy_and_delete_options: DirectoryMoveByCopyOptions,
    },
}

Describes the allowed strategies for moving a directory.

This ensures at least one of “rename” or “copy-and-delete” strategies are enabled at any point. Unless you have a good reason for picking something else, Self::Either is highly recommended. It ensures we always try to rename the directory if the conditions are right, and fall back to the slower copy-and-delete strategy if that fails.

Variants

OnlyRename

Disables the move by copy-and-delete strategy, leaving only the rename strategy.

If renaming fails, for example due to source and destination being on different mount points, the corresponding function will return ExecutionError(RenameFailedAndNoFallbackStrategy).

OnlyCopyAndDelete

Disables the move by rename strategy, leaving only the less efficient, but more general, copy-and-delete strategy.

Fields

options: DirectoryMoveByCopyOptions

Options for the copy-and-delete strategy.

Either

Enables both the rename and copy-and-delete strategies, leaving the optimal choice in the hands of the library.

Generally speaking, a rename will be attempted under the right conditions, with the copy-and-delete performed as a fallback if the rename fails.

Fields

copy_and_delete_options: DirectoryMoveByCopyOptions

Options for the copy-and-delete strategy.

Trait Implementations

impl Default for DirectoryMoveAllowedStrategies

fn default() -> Self

Returns the default directory move strategy configuration, which is with both rename and copy-and-delete enabled.
