Enum FormatStyle

#[non_exhaustive]
pub enum FormatStyle {
    Unknown,
    Metainfo,
    Catalog,
}

There are a few differences between AppStream’s metainfo files (shipped by upstream projects) and the catalog metadata (shipped by distributors). The data source kind indicates which style we should process. Usually you do not want to set this explicitly.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unknown

The format style is unknown.

Metainfo

Parse AppStream upstream metadata (metainfo files)

Catalog

Parse AppStream metadata catalog (shipped by software distributors)

impl Debug for FormatStyle

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

Formats the value using the given formatter.

impl From<FormatStyle> for Value

fn from(v: FormatStyle) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for FormatStyle

type Checker = GenericValueTypeChecker<FormatStyle>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for FormatStyle

type ParamSpec = ParamSpecEnum

type SetValue = FormatStyle

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

type BuilderFn = fn(_: &str, _: FormatStyle) -> ParamSpecEnumBuilder<'_, FormatStyle>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for FormatStyle

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 FormatStyle

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

impl PartialEq for FormatStyle

fn eq(&self, other: &FormatStyle) -> 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.

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.

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for FormatStyle

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for FormatStyle

type Type = FormatStyle

Type to get the Type from.

impl Copy for FormatStyle
