}

No-alloc display capability model derived from a parsed EDID.

Contains the same scalar fields as DisplayCapabilities plus a fixed-capacity mode list. Use MAX_MODES to set the maximum number of video modes that can be stored; 64 is a reasonable default for most displays (real displays rarely declare more than ~40 modes). Modes beyond the capacity are silently dropped, matching the behaviour of the 8-entry warning cap.

Produced by capabilities_from_edid_static.

Stack size

At MAX_MODES = 64 this struct is approximately 3 KB. On targets with very limited stack space, consider placing the value in a static mut or a statically-allocated buffer rather than on the stack.

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.
