Struct BlitterSupport 

pub struct BlitterSupport {
    pub half: bool,
    pub quad: bool,
    pub sextant: bool,
}

Available on crate feature crossterm only.

Runtime terminal capability probe (issue #264): read-only Capabilities snapshot plus the Blitter ladder it drives. Diagnostics-only — image rendering routes through the ladder automatically. Image-rendering primitives the terminal can drive, used to build the automatic blitter ladder. Each flag is conservative: when the runtime probe returns no answer the defaults assume only the universally available primitives (half-block + quadrants).

App code is not required to inspect this; it exists for diagnostics and to feed Capabilities::best_blitter.

Example

let blitters = ui.capabilities().blitters;
// Half-block is available on any ANSI terminal.
assert!(blitters.half);

Fields

half: bool

▀ upper-half block — available on any ANSI terminal.

quad: bool

▖▗▘▝ quadrant blocks — available on any Unicode-capable terminal.

sextant: bool

🬀..🬻 sextants (Unicode 13+) — off by default until a renderer confirms support. This issue wires the capability slot; a sextant renderer is a separate feature.
