Struct Budget 

#[non_exhaustive]
pub struct Budget {
    pub columns: u32,
    pub floors: u32,
}

What the columns kept at a cutoff ask for.

Counted in ch and in columns, and never in a host’s unit: each renderer turns it into its own with Budget::width, which is the one gap model every native renderer budgets by.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

columns: u32

How many columns are kept.

floors: u32

Their floors, summed, in ch.

Implementations

impl Budget

pub fn width(self, ch: f32, gap: f32) -> f32

The width these columns need, at ch per ch and gap between adjacent columns and at each edge.

floors * ch + gap * (columns + 1). A terminal passes one cell per ch and its column spacing; an immediate-mode painter passes the width of a figure and its cell padding on both sides. One formula, so a table drops a column at the same declared width in both.
