Struct 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 duplicate of the value.

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

Performs copy-assignment from source.

impl<P> Debug for LogicalPosition<P>

where P: Debug,

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> From<LogicalPosition<P>> for Position

where P: Pixel,

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

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)

Feeds a slice of this type into the given Hasher.

impl<P> PartialEq for LogicalPosition<P>

where P: PartialEq,

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.
