Struct font_types::Offset16

pub struct Offset16(/* private fields */);

A16-bit offset to a table.

Specific offset fields may or may not permit NULL values; however we assume that errors are possible, and expect the caller to handle the None case.

Implementations

impl Offset16

pub const fn new(raw: u16) -> Self

Create a new offset.

pub fn is_null(self) -> bool

Return true if this offset is null.

pub fn to_u32(self) -> u32

Trait Implementations

impl Clone for Offset16

fn clone(&self) -> Offset16

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Offset16

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

Formats the value using the given formatter.

impl Ord for Offset16

fn cmp(&self, other: &Offset16) -> 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<u32> for Offset16

fn eq(&self, other: &u32) -> 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 PartialEq for Offset16

fn eq(&self, other: &Offset16) -> 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 Offset16

fn partial_cmp(&self, other: &Offset16) -> 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 Offset16

type Raw = <u16 as Scalar>::Raw

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.

impl Zeroable for Offset16

fn zeroed() -> Self

Calls zeroed.
