Enum SyscallFlagError 

#[non_exhaustive]
pub enum SyscallFlagError<F: SyscallFlag> {
    #[non_exhaustive]
    NotSupported {
        flag: F,
        set: bool,
    },
}

Identifies errors when configuring a syscall flag.

Generic over the flag type to support different syscall flag categories. Each flag type implements SyscallFlag.

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.

#[non_exhaustive]

NotSupported

The requested flag configuration is not supported by the running kernel.

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.

flag: F

set: bool

Trait Implementations

impl<F: Debug + SyscallFlag> Debug for SyscallFlagError<F>

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

Formats the value using the given formatter.

impl<F> Display for SyscallFlagError<F>

where F: Debug + SyscallFlag,

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

Formats the value using the given formatter.

impl<F: SyscallFlag> Error for SyscallFlagError<F>

where Self: Debug + Display,

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.

impl From<SyscallFlagError<RestrictSelfFlag>> for RulesetError

fn from(source: SyscallFlagError<RestrictSelfFlag>) -> Self

Converts to this type from the input type.
