Enum Fixed 

#[non_exhaustive]
pub enum Fixed {
    First(u16),
    Second(u16),
}

An exact size for one child of a Split, overriding that split’s ratio.

The number is the child’s rendered extent along the split axis (columns for SplitDir::Vertical, rows for SplitDir::Horizontal) — the size that comes back from LayoutTree::window_rects, not an allocation the separator is later taken out of. First(30) and Second(30) both render 30 cells; the extra cell the separator needs is found for you.

This is deliberate: a dock’s width comes from user config, and the caller must never have to add one to compensate for a separator it can’t see.

The request is clamped so the sibling always keeps at least one cell — see LayoutTree::window_rects for the full geometry contract.

#[non_exhaustive] — additional variants may be added in minor releases.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

First(u16)

Render the first (top / left) child at exactly this many cells.

Second(u16)

Render the second (bottom / right) child at exactly this many cells.
