display-types

Shared display capability types for display connection negotiation.

This crate provides [DisplayCapabilities] and all its supporting types — the stable, typed model that EDID/DisplayID parsers produce and negotiation engines consume. It is the shared vocabulary between piaf (the parser) and concordance (the negotiation engine), and is suitable for any crate that needs to describe display capabilities without taking a dependency on a full parser.

Feature flags

Flag	Default	Description
`std`	yes	Enables `std`-dependent types; implies `alloc`.
`alloc`	no	Enables heap-allocated types (`Vec`, `Arc`, `String`) without full `std`.
`serde`	no	Derives `Serialize`/`Deserialize` for all public types.

With neither std nor alloc the crate compiles in bare no_std mode and exposes only the scalar types (enums and copy structs).

Usage

cargo add display-types

For no_std with heap allocation (e.g. embedded with an allocator):

cargo add display-types --no-default-features --features alloc

For bare no_std (scalars only):

cargo add display-types --no-default-features
