Destination directory path validation error.

Variants

NotADirectory

The base source path (path to the directory you want to copy) exists, but does not point to a directory.

Fields

directory_path: PathBuf

Destination directory path.

UnableToAccess

The destination directory could not be read, or its path could not be canonicalized.

Among other things, this can happen due to missing read permissions.

The inner std::io::Error will likely describe a more precise cause of this error.

Fields

directory_path: PathBuf

The exact path we were unable to access.

error: Error

IO error describing why the source directory could not be accessed.

AlreadyExists

A destination directory or a file inside it already exists, which is against the provided DestinationDirectoryRule.

Fields

path: PathBuf

Path to the file or directory that should not exist based on the provided rules.

destination_directory_rule: DestinationDirectoryRule

Destination directory rule that made the existing destination directory invalid (see DestinationDirectoryRule::DisallowExisting).

NotEmpty

A destination directory or a file inside it exists and is not empty, which is against the provided DestinationDirectoryRule.

Fields

directory_path: PathBuf

Path to the destination directory that should be empty based on the provided rules.

destination_directory_rule: DestinationDirectoryRule

Destination directory rule that made the existing destination directory invalid (see DestinationDirectoryRule::AllowEmpty).

DescendantOfSourceDirectory

The destination directory path equals or points inside the source directory, which is very problematic for copies or moves.

Fields

destination_directory_path: PathBuf

Invalid destination directory path.

source_directory_path: PathBuf

Corresponding source directory path.

Trait Implementations

impl Debug for DestinationDirectoryPathValidationError

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

Formats the value using the given formatter.

impl Display for DestinationDirectoryPathValidationError

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

Formats the value using the given formatter.

impl Error for DestinationDirectoryPathValidationError

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.
