Struct LogicalPosition

pub struct LogicalPosition {
    pub x: f64,
    pub y: f64,
}

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: f64

y: f64

Implementations

impl LogicalPosition

pub fn new(x: f64, y: f64) -> LogicalPosition

pub fn from_physical<T>(physical: T, dpi_factor: f64) -> LogicalPosition

where T: Into<PhysicalPosition>,

pub fn to_physical(&self, dpi_factor: f64) -> PhysicalPosition

Trait Implementations

impl Clone for LogicalPosition

fn clone(&self) -> LogicalPosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogicalPosition

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

Formats the value using the given formatter.

impl From<(f64, f64)> for LogicalPosition

fn from(_: (f64, f64)) -> LogicalPosition

Converts to this type from the input type.

impl From<(i32, i32)> for LogicalPosition

fn from(_: (i32, i32)) -> LogicalPosition

Converts to this type from the input type.

impl Into<(f64, f64)> for LogicalPosition

fn into(self) -> (f64, f64)

Converts this type into the (usually inferred) input type.

impl Into<(i32, i32)> for LogicalPosition

fn into(self) -> (i32, i32)

Note that this rounds instead of truncating.

impl PartialEq for LogicalPosition

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