Enum landlock::PathBeneathError

#[non_exhaustive]
pub enum PathBeneathError {
    StatCall {
        source: Error,
    },
    DirectoryAccess {
        access: BitFlags<AccessFs>,
        incompatible: BitFlags<AccessFs>,
    },
}

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.

StatCall

To check that access-rights are consistent with a file descriptor, a call to RulesetCreatedAttr::add_rule() looks at the file type with an fstat() system call.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

source: Error

DirectoryAccess

This error is returned by RulesetCreatedAttr::add_rule() if the related PathBeneath object is not set to best-effort, and if its allowed access-rights contain directory-only ones whereas the file descriptor doesn’t point to a directory.

Fields

access: BitFlags<AccessFs>

incompatible: BitFlags<AccessFs>

Trait Implementations

impl Debug for PathBeneathError

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

Formats the value using the given formatter.

impl Display for PathBeneathError

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

Formats the value using the given formatter.

impl Error for PathBeneathError

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

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.

impl<T> From<PathBeneathError> for CompatError<T>

where T: Access,

fn from(source: PathBeneathError) -> Self

Converts to this type from the input type.
