Struct Chat

    pub id: String,
    pub chat_type: ChatType,
    pub participants: Vec<u16>,
    pub messages: CompactMessageVec,
    pub last_read: [u8; 32],
    pub created_at: u64,

Fields

id: String

chat_type: ChatType

participants: Vec<u16>

messages: CompactMessageVec

last_read: [u8; 32]

created_at: u64

metadata: ChatMetadata

muted: bool

typing_participants: Vec<(u16, u64)>

wallpaper_path: String

Local cached file path for the per-DM wallpaper, or empty when unset. Populated from the most recent kind-30078 d=vector-wallpaper rumor received for this chat (the encrypted Blossom file is fetched and decrypted to this path).

wallpaper_ts: u64

Rumor created_at (Unix seconds) that produced the current wallpaper. Used as the latest-write-wins tiebreaker on concurrent sets.

wallpaper_blur: u8

Blur amount in pixels applied to the wallpaper background layer (0..=30, clamped on read). 0 means no blur.

wallpaper_dim: u8

Brightness percent applied to the wallpaper background layer (0..=100, clamped on read). 100 means no darkening; 0 is fully dim. Default 70 keeps text readable on photographic wallpapers.

wallpaper_url: String

Blossom URL of the encrypted wallpaper blob currently in effect. Used to DELETE the previous blob when we (or our other device) replace the wallpaper, so stale uploads don’t linger on servers.

wallpaper_uploader: String

npub (bech32) of whichever account uploaded the current wallpaper. Gate on this before issuing the Blossom DELETE — only the original uploader’s signature satisfies the server’s auth challenge.
