Struct Revision

#[repr(transparent)]
pub struct Revision(pub u32);

A revision of the UEFI specification.

The major revision number is incremented on major, API-incompatible changes.

The minor revision number is incremented on minor changes, it is stored as a two-digit binary-coded decimal.

Display format

For major revision 2 and later, if the lower minor digit is zero, the revision is formatted as “major.minor-upper”. Otherwise it’s formatted as “major.minor-upper.minor-lower”. This format is described in the “EFI System Table” section of the UEFI Specification.

Prior to major version 2, the revision is always formatted as “major.minor”, with minor left-padded with zero if minor-upper is zero.

Examples:

assert_eq!(Revision::EFI_1_02.to_string(), "1.02");
assert_eq!(Revision::EFI_1_10.to_string(), "1.10");
assert_eq!(Revision::EFI_2_00.to_string(), "2.0");
assert_eq!(Revision::EFI_2_30.to_string(), "2.3");
assert_eq!(Revision::EFI_2_31.to_string(), "2.3.1");
assert_eq!(Revision::EFI_2_100.to_string(), "2.10");

impl Revision

pub const fn new(major: u16, minor: u16) -> Self

Returns the major revision.

pub const fn minor(self) -> u16

Returns the minor revision.

Trait Implementations

impl Clone for Revision

fn clone(&self) -> Revision

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Revision

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

Formats the value using the given formatter.

impl Default for Revision

fn default() -> Revision

Returns the “default value” for a type.

impl Display for Revision

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

Formats the value using the given formatter.

impl Hash for Revision

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 Revision

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

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

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