Crate hashavatar 

Procedural, asset-free avatar generation driven by stable identity hashes.

The crate produces deterministic avatar images from an input identifier without shipping image packs, sprites, or third-party artwork. All visual output is drawn from code using geometric primitives.

Typical usage:

use hashavatar::{
    AvatarBackground, AvatarKind, AvatarOptions, AvatarOutputFormat, AvatarSpec,
    encode_avatar_for_id,
};

let bytes = encode_avatar_for_id(
    AvatarSpec::new(256, 256, 0),
    "alice@example.com",
    AvatarOutputFormat::WebP,
    AvatarOptions {
        kind: AvatarKind::Robot,
        background: AvatarBackground::White,
    },
)?;
