Struct cosmic::iced_widget::renderer::graphics::text::cosmic_text::fontdb::ID

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

A unique per database face ID.

Since Database is not global/unique, we cannot guarantee that a specific ID is actually from the same db instance. This is up to the caller.

ID overflow will cause a panic, but it’s highly unlikely that someone would load more than 4 billion font faces.

Because the internal representation of ID is private, The Display trait implementation for this type only promise that unequal IDs will be displayed as different strings, but does not make any guarantees about format or content of the strings.

Implementations

impl ID

pub fn dummy() -> ID

Creates a dummy ID.

Should be used in tandem with Database::push_face_info.

Trait Implementations

impl Clone for ID

fn clone(&self) -> ID

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ID

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

Formats the value using the given formatter.

impl Default for ID

fn default() -> ID

Returns the “default value” for a type.

impl Display for ID

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

Formats the value using the given formatter.

impl Hash for ID

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 Ord for ID

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

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

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