Struct Look 

pub struct Look<'a> {
    pub app: &'a str,
    pub record: &'a str,
    pub kind: &'a str,
    pub doc: &'a AutoCommit,
    pub tree: Option<&'a AutoCommit>,
    pub quiet: bool,
    pub read: &'a dyn Fn(&Embed) -> Reading,
}

A record as an inbox looks at it.

Fields

app: &'a str

The app keeping it.

record: &'a str

The record, as its route names it: empty for the app’s own record of the workspace.

kind: &'a str

The kind of the app’s records, for a record (or chain) whose document names none, as the app’s own record of the workspace does.

doc: &'a AutoCommit

Its document.

tree: Option<&'a AutoCommit>

The record its places belong to, when it is a part of another (a chat’s part, published as the chat’s items): its document.

quiet: bool

Take what it holds as seen: the person is looking at it, or it is what the workspace held before this device first followed it.

read: &'a dyn Fn(&Embed) -> Reading

How a reference in its text reads for the person told: what a notice’s excerpt says of it (reading_nothing where nobody here can tell what they hold).
