Struct dpi::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 noticeable issues. To help with that, an Into<(i32, i32)> implementation is provided which does the rounding for you.

Fields

x: P

y: P

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

impl<P: Pixel> From<LogicalPosition<P>> for Position

fn from(position: LogicalPosition<P>) -> Position

impl<P: Hash> Hash for LogicalPosition<P>

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<P: Ord> Ord for LogicalPosition<P>

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> PartialEq for LogicalPosition<P>

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

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.
