Enum Unpreserved 

#[non_exhaustive]
pub enum Unpreserved {
    ReadOnly,
    Encrypted,
    Owner,
    Group,
    Mode,
    Acl,
}

What a replacement file would not keep of the file it replaces, found before anything was written. See “What a replacement keeps” in the module docs for what is, and is not, examined on each platform.

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.

ReadOnly

The file is read-only (Windows attribute).

Encrypted

The file is EFS-encrypted (Windows attribute); the replacement would be plaintext.

Owner

The replacement would have a different owner (Unix).

Group

The replacement would have a different group (Unix).

Mode

The replacement would have different permission bits (Unix).

Acl

The file is owner-only and has, or may have, an extended ACL the replacement would not carry, or the replacement itself got one (macOS).

Trait Implementations

impl Eq for Unpreserved

impl Error for Unpreserved

fn source(&self) -> Option<&(dyn Error + 'static)>

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.
