Struct font_types::MajorMinor

#[repr(C)]
pub struct MajorMinor {
    pub major: u16,
    pub minor: u16,
}

A type representing a major, minor version pair.

This is not part of the spec, but versions in the spec are frequently represented as a major_version, minor_version pair. This type encodes those as a single type, which is useful for some of the generated code that parses out a version.

Fields

major: u16

The major version number

minor: u16

The minor version number

Trait Implementations

impl Clone for MajorMinor

fn clone(&self) -> MajorMinor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Compatible<(u16, u16)> for MajorMinor

fn compatible(&self, other: (u16, u16)) -> bool

return true if this version is field-compatible with other.

impl Compatible for MajorMinor

fn compatible(&self, other: Self) -> bool

return true if this version is field-compatible with other.

impl Debug for MajorMinor

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

Formats the value using the given formatter.

impl Default for MajorMinor

fn default() -> MajorMinor

Returns the “default value” for a type.

impl Display for MajorMinor

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

Formats the value using the given formatter.

impl Hash for MajorMinor

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 MajorMinor

fn cmp(&self, other: &MajorMinor) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for MajorMinor

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for MajorMinor

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Scalar for MajorMinor

type Raw = [u8; 4]

The raw byte representation of this type.

fn from_raw(raw: Self::Raw) -> Self

Create an instance of this type from raw big-endian bytes

fn to_raw(self) -> Self::Raw

Encode this type as raw big-endian bytes

fn read(slice: &[u8]) -> Option<Self>

Attempt to read a scalar from a slice.
