Struct ContentRating

pub struct ContentRating { /* private fields */ }

Implements

ContentRatingExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl ContentRating

pub const NONE: Option<&'static ContentRating> = None

pub fn new() -> ContentRating

Creates a new ContentRating.

Returns

a ContentRating

pub fn attribute_from_csm_age(id: &str, age: u32) -> ContentRatingValue

Gets the highest ContentRatingValue which is allowed to be seen by the given Common Sense Media age for the given subsection id.

For example, if the CSM age mappings for violence-bloodshed are:

• age ≥ 0 for ContentRatingValue::None
• age ≥ 9 for ContentRatingValue::Mild
• age ≥ 11 for ContentRatingValue::Moderate
• age ≥ 18 for ContentRatingValue::Intense then calling this function with violence-bloodshed and age set to 17 would return ContentRatingValue::Moderate. Calling it with age 18 would return ContentRatingValue::Intense.

id

the subsection ID e.g. violence-cartoon

age

the CSM age

Returns

the ContentRatingValue, or ContentRatingValue::Unknown if unknown

pub fn attribute_get_description( id: &str, value: ContentRatingValue, ) -> Option<GString>

Get a human-readable description of what content would be expected to require the content rating attribute given by id and value.

id

the subsection ID e.g. violence-cartoon

value

the ContentRatingValue, e.g. ContentRatingValue::Intense

Returns

a human-readable description of id and value

pub fn attribute_to_csm_age(id: &str, value: ContentRatingValue) -> u32

Gets the Common Sense Media approved age for a specific rating level.

id

the subsection ID e.g. violence-cartoon

value

the ContentRatingValue, e.g. ContentRatingValue::Intense

Returns

The age in years, or 0 for no details.

pub fn all_rating_ids() -> Vec<GString>

Returns a list of all the valid OARS content rating attribute IDs as could be passed to ContentRatingExt::add_attribute() or attribute_to_csm_age().

Returns

a None-terminated array of IDs, to be freed with g_free() (the element values are owned by libappstream and must not be freed)

Trait Implementations

impl Clone for ContentRating

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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

Performs copy-assignment from source.

impl Debug for ContentRating

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

Formats the value using the given formatter.

impl Default for ContentRating

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for ContentRating

type ParamSpec = ParamSpecObject

type SetValue = ContentRating

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, ContentRating>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ContentRating

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

where H: Hasher,

Hashes the memory address of this object.

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 ContentRating

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

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 ParentClassIs for ContentRating

type Parent = Object

impl<OT: ObjectType> PartialEq<OT> for ContentRating

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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<OT: ObjectType> PartialOrd<OT> for ContentRating

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

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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 StaticType for ContentRating

fn static_type() -> Type

Returns the type identifier of Self.
