Struct Status

#[repr(transparent)]
pub struct Status(pub usize);

UEFI uses status codes in order to report successes, errors, and warnings.

The spec allows implementation-specific status codes, so the Status constants are not a comprehensive list of all possible values.

Tuple Fields

0: usize

pub const WARN_DELETE_FAILURE: Status

The handle was closed, but the file was not deleted.

pub const WARN_WRITE_FAILURE: Status

The handle was closed, but the data to the file was not flushed properly.

pub const WARN_BUFFER_TOO_SMALL: Status

The resulting buffer was too small, and the data was truncated.

pub const END_OF_FILE: Status

The end of the file was reached.

pub const INVALID_LANGUAGE: Status

The language specified was invalid.

pub const COMPROMISED_DATA: Status

The security status of the data is unknown or compromised and the data must be updated or replaced to restore a valid security status.

pub const IP_ADDRESS_CONFLICT: Status

There is an address conflict address allocation

pub const HTTP_ERROR: Status

A HTTP error occurred during the network operation.

impl Status

pub const ERROR_BIT: usize = 9_223_372_036_854_775_808usize

Bit indicating that an UEFI status code is an error.

pub fn is_success(self) -> bool

Returns true if status code indicates success.

pub fn is_warning(self) -> bool

Returns true if status code indicates a warning.

pub const fn is_error(self) -> bool

Returns true if the status code indicates an error.

Trait Implementations

impl Clone for Status

fn clone(&self) -> Status

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Status

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

Formats the value using the given formatter.

impl Display for Status

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

Formats the value using the given formatter.

impl Hash for Status

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 Status

fn cmp(&self, other: &Status) -> 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 Status

fn eq(&self, other: &Status) -> 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 Status

fn partial_cmp(&self, other: &Status) -> 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.
