SmallGlyphMetrics record.

Fields

height: u8

Number of rows of data.

width: u8

Number of columns of data.

bearing_x: BigEndian<i8>

Distance in pixels from the horizontal origin to the left edge of the bitmap (for horizontal text); or distance in pixels from the vertical origin to the top edge of the bitmap (for vertical text).

bearing_y: BigEndian<i8>

Distance in pixels from the horizontal origin to the top edge of the bitmap (for horizontal text); or distance in pixels from the vertical origin to the left edge of the bitmap (for vertical text).

advance: u8

Horizontal or vertical advance width in pixels.

Implementations

impl SmallGlyphMetrics

pub fn height(&self) -> u8

Number of rows of data.

pub fn width(&self) -> u8

Number of columns of data.

pub fn bearing_x(&self) -> i8

Distance in pixels from the horizontal origin to the left edge of the bitmap (for horizontal text); or distance in pixels from the vertical origin to the top edge of the bitmap (for vertical text).

pub fn bearing_y(&self) -> i8

Distance in pixels from the horizontal origin to the top edge of the bitmap (for horizontal text); or distance in pixels from the vertical origin to the left edge of the bitmap (for vertical text).

pub fn advance(&self) -> u8

Horizontal or vertical advance width in pixels.

Trait Implementations

impl Clone for SmallGlyphMetrics

fn clone(&self) -> SmallGlyphMetrics

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SmallGlyphMetrics

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

Formats the value using the given formatter.

impl FixedSize for SmallGlyphMetrics

const RAW_BYTE_LEN: usize = 5usize

The raw size of this type, in bytes.

impl Hash for SmallGlyphMetrics

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 SmallGlyphMetrics

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

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

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

impl Zeroable for SmallGlyphMetrics

fn zeroed() -> Self

Calls zeroed.
