Struct FracVal 

pub struct FracVal(i64);

An f32 quantized to units of 2⁻²⁴ (truncated toward zero), stored as i64. NOTE: f32 -> FracVal on NaN saturates to 0 (Rust as cast). Reject NaN at command construction (debug_assert) rather than relying on saturation.

Tuple Fields

0: i64

Implementations

impl FracVal

pub const LIMIT: i64

±2²⁴ in screen coordinates; sums of two stay exact in i64. Same refuse-don’t-clamp rule as GRID_LIMIT.

Trait Implementations

impl Clone for FracVal

fn clone(&self) -> FracVal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FracVal

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

Formats the value using the given formatter.

impl Default for FracVal

fn default() -> FracVal

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FracVal

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<FracVal> for f32

fn from(val: FracVal) -> f32

Converts to this type from the input type.

impl From<f32> for FracVal

fn from(val: f32) -> FracVal

Converts to this type from the input type.

impl Hash for FracVal

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 FracVal

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

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

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

impl Serialize for FracVal

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<i64> for FracVal

type Error = OutOfExtent

The type returned in the event of a conversion error.

fn try_from(raw: i64) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for FracVal

impl Eq for FracVal
