Struct Cursor 

pub struct Cursor(/* private fields */);

An opaque feed position issued by the provider.

Cursors are ordered by the provider’s commits, are stable across restarts and are never reused, but apps never parse them or compare their order: they only pass one back as a read’s after. This type therefore has no ordering; equality only says two values are the same cursor string.

Implementations

impl Cursor

pub fn new(cursor: impl Into<String>) -> Self
