Struct Boolean 

#[repr(transparent)]
pub struct Boolean(pub u8);

ABI-compatible UEFI boolean.

This is similar to a bool, but allows values other than 0 or 1 to be stored without it being undefined behavior.

Any non-zero value is treated as logical true. The comparison, ordering, and hashing implementations follow that logical interpretation, so all non-zero values compare equal and hash the same way. The original byte is still preserved in the public field; compare the .0 values directly when the exact raw bit pattern matters.

Tuple Fields

0: u8

Implementations

impl Boolean

pub const TRUE: Self

Boolean representing true.

Caution

This is only one possible true bit pattern. In UEFI, every non-zero bit pattern is treated as logical true.

pub const FALSE: Self

Boolean representing false.

Trait Implementations

impl Clone for Boolean

fn clone(&self) -> Boolean

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Boolean

impl Debug for Boolean

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

Formats the value using the given formatter.

impl Default for Boolean

fn default() -> Boolean

Returns the “default value” for a type.

impl Eq for Boolean

impl From<Boolean> for bool

fn from(value: Boolean) -> Self

Converts to this type from the input type.

impl From<bool> for Boolean

fn from(value: bool) -> Self

Converts to this type from the input type.

impl From<u8> for Boolean

fn from(value: u8) -> Self

Converts to this type from the input type.

impl Hash for Boolean

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 Boolean

fn cmp(&self, other: &Self) -> 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 Boolean

fn eq(&self, other: &Self) -> 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 Boolean

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