Struct FontId 

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

A registered font (Core::add_font_data / add_system_font), used through TextStyle::font.

Implementations

impl FontId

pub fn to_ffi(self) -> u64

The handle as a plain integer for C/Lua/JS (generation check intact).

pub fn from_ffi(raw: u64) -> FontId

Trait Implementations

impl Clone for FontId

fn clone(&self) -> FontId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FontId

impl Debug for FontId

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

Formats the value using the given formatter.

impl Default for FontId

fn default() -> FontId

Returns the “default value” for a type.

impl Eq for FontId

impl From<KeyData> for FontId

fn from(k: KeyData) -> FontId

Converts to this type from the input type.

impl Hash for FontId

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Key for FontId

fn data(&self) -> KeyData

Gets the KeyData stored in this key.

fn null() -> Self

Creates a new key that is always invalid and distinct from any non-null key. A null key can only be created through this method (or default initialization of keys made with new_key_type!, which calls this method).

fn is_null(&self) -> bool

Checks if a key is null. There is only a single null key, that is a.is_null() && b.is_null() implies a == b.

impl Ord for FontId

fn cmp(&self, other: &FontId) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for FontId

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for FontId

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