Struct Dp 

pub struct Dp(pub f64);

Density-independent layout units, converted using the active session’s scale.

use tessera_ui::{Dp, RuntimeSession, dp::set_scale_factor};
let session = RuntimeSession::new();
let _scope = session.enter();
set_scale_factor(1.5);
assert_eq!(Dp(8.0).to_pixels_f64(), 12.0);
assert_eq!(Dp::from_pixels_f64(12.0), Dp(8.0));

Implementations

impl Dp

pub const ZERO: Dp

A constant representing zero density-independent pixels.

pub const fn new(value: f64) -> Self

Creates a new Dp instance with the specified value.

pub fn to_pixels_f64(&self) -> f64

Scales to physical pixels using the active session’s density.

pub fn from_pixels_f64(value: f64) -> Self

Converts physical pixels using the active session’s density.

pub fn to_pixels_u32(&self) -> u32

Scales to physical pixels, truncating toward zero and saturating to u32.

pub fn from_pixels_u32(value: u32) -> Self

Converts physical pixels using the active session’s density.

pub fn to_pixels_f32(&self) -> f32

Scales to physical pixels with f32 precision.

pub fn from_pixels_f32(value: f32) -> Self

Converts physical pixels using the active session’s density.

pub fn to_px(&self) -> Px

Scales to whole physical pixels, truncating the fractional part.
