Struct rusttype::VMetrics

pub struct VMetrics {
    pub ascent: f32,
    pub descent: f32,
    pub line_gap: f32,
}

The "vertical metrics" of a font at a particular scale. This is useful for calculating the amount of vertical space to give a line of text, and for computing the vertical offset between successive lines.

Fields

ascent: f32

The highest point that any glyph in the font extends to above the baseline. Typically positive.

descent: f32

The lowest point that any glyph in the font extends to below the baseline. Typically negative.

line_gap: f32

The gap to leave between the descent of one line and the ascent of the next. This is of course only a guideline given by the font's designers.

Trait Implementations

impl PartialOrd<VMetrics> for VMetrics

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

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

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

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

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

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

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

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

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

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

impl PartialEq<VMetrics> for VMetrics

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

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

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

This method tests for !=.

impl From<VMetrics> for VMetrics

fn from(vm: VMetrics) -> Self

Performs the conversion.

impl Clone for VMetrics

fn clone(&self) -> VMetrics

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for VMetrics

impl Debug for VMetrics

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

Formats the value using the given formatter.

impl Mul<f32> for VMetrics

type Output = VMetrics

The resulting type after applying the * operator.

fn mul(self, rhs: f32) -> Self

Performs the * operation.
