Struct Sp 

pub struct Sp(pub f32);

Scale-independent pixels: a text size that follows both the device’s pixel density and the user’s font-scale accessibility setting. Distinct from Dp because a length must not move when the user’s text-size setting does, and a text size must.

Tuple Fields

0: f32

Implementations

impl Sp

pub const ZERO: Self

pub fn max(self, other: Self) -> Self

The larger of two lengths in the same unit. Comparing across units (a Dp against an Sp) is exactly the mistake this module exists to make impossible, so this does not accept one.

pub fn min(self, other: Self) -> Self

The smaller of two lengths in the same unit.

impl Sp

pub fn to_px(self, density: Density) -> Px

Converts to the actual device pixel count on density’s grid, scaled by the user’s font-scale setting on top of pixel density.

pub fn from_px(px: Px, density: Density) -> Self

Recovers the Sp that produced px on density’s grid.
