pub fn capabilities() -> CapabilitiesAvailable on crate feature
crossterm only.Expand description
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.
Return the process-global negotiated Capabilities, probing the terminal
exactly once on first call and caching the result.
The probe issues DA1 (CSI c), DA2 (CSI > c), and XTGETTCAP for the
truecolor capname, reading replies through the existing OSC round-trip
infrastructure with a bounded total timeout (≤150ms). On no reply every
field falls back to a conservative default. Repeated calls are free.
