Struct EfiStatus

#[repr(transparent)]
pub struct EfiStatus(pub u64);

UEFI spec Appendix D - Status Codes

Note that EFI_STATUS is encoded as a UINTN in UEFI, so it is either 32 or 64 bits wide (with the error bit always being the high bit). This enum is defined as 64 bits wide so that it does not lose any (invalid) high bits when taking a guest-provided 64-bit value.

However, this type is not intended for direct sharing with the guest, so it does not derive IntoBytes, etc. To be clear about intent when using this value for communication with the guest via shared memory, use EfiStatus64 instead. If you are implementing a legacy protocol that does not preserve the error bit, use EfiStatus64NoErrorBit.

Trait Implementations

impl Clone for EfiStatus

fn clone(&self) -> EfiStatus

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EfiStatus

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

Formats the value using the given formatter.

impl Default for EfiStatus

fn default() -> Self

Returns the “default value” for a type.

impl From<EfiStatus> for EfiStatus64

fn from(value: EfiStatus) -> Self

Converts to this type from the input type.

impl From<EfiStatus> for EfiStatus64NoErrorBit

fn from(value: EfiStatus) -> Self

Converts to this type from the input type.

impl From<EfiStatus64> for EfiStatus

fn from(value: EfiStatus64) -> Self

Converts to this type from the input type.

impl From<EfiStatus64NoErrorBit> for EfiStatus

fn from(value: EfiStatus64NoErrorBit) -> Self

Converts to this type from the input type.

impl Hash for EfiStatus

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for EfiStatus

fn cmp(&self, other: &EfiStatus) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for EfiStatus

fn eq(&self, other: &EfiStatus) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for EfiStatus

fn partial_cmp(&self, other: &EfiStatus) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
