Struct screen_13::prelude::LogicalPosition

pub struct LogicalPosition<P> {
    pub x: P,
    pub y: P,
}

A position represented in logical pixels.

The position is stored as floats, so please be careful. Casting floats to integers truncates the fractional part, which can cause noticable issues. To help with that, an Into<(i32, i32)> implementation is provided which does the rounding for you.

Fields

x: P

y: P

Trait Implementations

impl<P> Clone for LogicalPosition<P>

where P: Clone,

fn clone(&self) -> LogicalPosition<P>

Returns a copy of the value.

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

Performs copy-assignment from source.

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

Formats the value using the given formatter.

impl<P> Default for LogicalPosition<P>

where P: Default,

fn default() -> LogicalPosition<P>

Returns the “default value” for a type.

impl<P, X> From<[X; 2]> for LogicalPosition<P>

where P: Pixel, X: Pixel,

fn from(_: [X; 2]) -> LogicalPosition<P>

Converts to this type from the input type.

impl<P, X> From<(X, X)> for LogicalPosition<P>

where P: Pixel, X: Pixel,

fn from(_: (X, X)) -> LogicalPosition<P>

Converts to this type from the input type.

impl<P> Hash for LogicalPosition<P>

where P: Hash,

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<P> Ord for LogicalPosition<P>

where P: Ord,

fn cmp(&self, other: &LogicalPosition<P>) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl<P> PartialEq for LogicalPosition<P>

where P: PartialEq,

fn eq(&self, other: &LogicalPosition<P>) -> 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<P> PartialOrd for LogicalPosition<P>

where P: PartialOrd,

fn partial_cmp(&self, other: &LogicalPosition<P>) -> 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.
