Enum ScaleType

#[repr(i32)]
pub enum ScaleType {
    None = 0,
    UnitLinearScale = 1,
    UnitLogScale = 2,
    UnitReverseLogScale = 3,
}

The type of scaling that should be applied to this parameter.

Variants

None = 0

By default, no scaling is applied.

UnitLinearScale = 1

Scales the feasible space to (0, 1) linearly.

UnitLogScale = 2

Scales the feasible space logarithmically to (0, 1). The entire feasible space must be strictly positive.

UnitReverseLogScale = 3

Scales the feasible space “reverse” logarithmically to (0, 1). The result is that values close to the top of the feasible space are spread out more than points near the bottom. The entire feasible space must be strictly positive.

Implementations

impl ScaleType

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of ScaleType.

pub fn from_i32(value: i32) -> Option<ScaleType>

Converts an i32 to a ScaleType, or None if value is not a valid variant.

Trait Implementations

impl Clone for ScaleType

fn clone(&self) -> ScaleType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScaleType

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

Formats the value using the given formatter.

impl Default for ScaleType

fn default() -> ScaleType

Returns the “default value” for a type.

impl From<ScaleType> for i32

fn from(value: ScaleType) -> i32

Converts to this type from the input type.

impl Hash for ScaleType

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 ScaleType

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

impl PartialEq for ScaleType

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

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