Enum gegl::ResolutionUnit

#[non_exhaustive]
pub enum ResolutionUnit {
    None,
    Dpi,
    Dpm,
}

An enumerated type specifying resolution (density) units. If resolution units are unknown, X and Y resolution specify the pixel aspect ratio.

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.

None

Unknown or resolution not applicable.

Dpi

Dots or pixels per inch.

Dpm

Dots or pixels per metre.

Performs copy-assignment from source.

impl Debug for ResolutionUnit

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

Formats the value using the given formatter.

impl From<ResolutionUnit> for Value

fn from(v: ResolutionUnit) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for ResolutionUnit

type Checker = GenericValueTypeChecker<ResolutionUnit>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for ResolutionUnit

type ParamSpec = ParamSpecEnum

type SetValue = ResolutionUnit

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ResolutionUnit

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 ResolutionUnit

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<ResolutionUnit> for ResolutionUnit

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

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

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

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

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

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

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

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

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

Returns the type identifier of Self.

impl ToValue for ResolutionUnit

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type
