Enum SheetSize 

pub enum SheetSize {
    OneThird,
    Half,
    TwoThirds,
    Ratio(f32),
    Pixels(f32),
}

The size a sheet should occupy along the axis perpendicular to its anchor edge.

• For a top- or bottom-anchored sheet, SheetSize is a height.
• For a start- or end-anchored sheet, SheetSize is a width.

Use the named variants for canonical proportions; use SheetSize::Ratio for arbitrary fractions (clamped to 0.0..=1.0); use SheetSize::Pixels for a fixed pixel size independent of window dimensions (discouraged for responsive apps).

Variants

OneThird

33 % of the window’s relevant axis — the default “drawer” size.

Half

50 % of the window’s relevant axis.

TwoThirds

67 % of the window’s relevant axis.

Ratio(f32)

Arbitrary fraction of the window’s relevant axis. Values outside 0.0..=1.0 are clamped by the engine.

Pixels(f32)

Fixed pixel size. Only use when the content has a natural size that does not scale with the window.

Implementations

impl SheetSize

pub const DEFAULT: SheetSize = SheetSize::OneThird

The default size — one-third of the window.

pub fn as_ratio(self) -> Option<f32>

Resolve to a fraction of the relevant axis, if this variant expresses one. Returns None for SheetSize::Pixels.

Example

use snora_core::SheetSize;

assert_eq!(SheetSize::Half.as_ratio(), Some(0.5));
assert_eq!(SheetSize::Ratio(1.5).as_ratio(), Some(1.0)); // clamped
assert_eq!(SheetSize::Pixels(240.0).as_ratio(), None);

pub fn as_pixels(self) -> Option<f32>

Resolve to a pixel value, if this variant expresses one. Returns None for the ratio-based variants.

Example

use snora_core::SheetSize;

assert_eq!(SheetSize::Pixels(280.0).as_pixels(), Some(280.0));
assert_eq!(SheetSize::Half.as_pixels(), None);
