Struct usvgr::NonZeroPositiveF64

#[repr(transparent)]
pub struct NonZeroPositiveF64(_);

An immutable, finite f64 that is known to be > 0.

Implementations

impl NonZeroPositiveF64

pub fn new(n: f64) -> Option<NonZeroPositiveF64>

Creates a new NonZeroPositiveF64 if the given value is > 0.

Returns None for negative, zero, NaN and infinity.

pub const unsafe fn new_unchecked(n: f64) -> NonZeroPositiveF64

Creates a new NonZeroPositiveF64 without checking the value.

Safety

n must be finite and > 0.

pub const fn get(&self) -> f64

Returns the value as a primitive type.

pub const fn get_finite(&self) -> FiniteF64

Returns the value as a FiniteF64.

Trait Implementations

impl ApproxEq for NonZeroPositiveF64

type Margin = F64Margin

This type type defines a margin within which two values are to be considered approximately equal. It must implement Default so that approx_eq() can be called on unknown types.

fn approx_eq<M>(self, other: NonZeroPositiveF64, margin: M) -> boolwhere
    M: Into<<NonZeroPositiveF64 as ApproxEq>::Margin>,

This method tests that the self and other values are equal within margin of each other.

fn approx_ne<M>(self, other: Self, margin: M) -> boolwhere
    M: Into<Self::Margin>,

This method tests that the self and other values are not within margin of each other.

impl ApproxEqUlps for NonZeroPositiveF64

type Flt = f64

fn approx_eq_ulps(&self, other: &NonZeroPositiveF64, ulps: i64) -> bool

This method tests for self and other values to be approximately equal within ULPs (Units of Least Precision) floating point representations. Differing signs are always unequal with this method, and zeroes are only equal to zeroes. Use approx_eq() from the ApproxEq trait if that is more appropriate.

fn approx_ne_ulps(&self, other: &Self, ulps: <Self::Flt as Ulps>::U) -> bool

This method tests for self and other values to be not approximately equal within ULPs (Units of Least Precision) floating point representations. Differing signs are always unequal with this method, and zeroes are only equal to zeroes. Use approx_eq() from the ApproxEq trait if that is more appropriate.

impl Clone for NonZeroPositiveF64

fn clone(&self) -> NonZeroPositiveF64

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NonZeroPositiveF64

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

Formats the value using the given formatter.

impl Display for NonZeroPositiveF64

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

Formats the value using the given formatter.

impl Hash for NonZeroPositiveF64

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,

Feeds a slice of this type into the given Hasher.

impl Ord for NonZeroPositiveF64

fn cmp(&self, other: &NonZeroPositiveF64) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<NonZeroPositiveF64> for NonZeroPositiveF64

fn eq(&self, other: &NonZeroPositiveF64) -> 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.

impl PartialOrd<NonZeroPositiveF64> for NonZeroPositiveF64

fn partial_cmp(&self, other: &NonZeroPositiveF64) -> 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.

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

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.
