Tapbacks

Tapbacks look like normal messages in the database. Only the latest tapback state is stored. For example:

• user receives message -> user likes message
  • This creates a message and a like message.
• user receives message -> user likes message -> user unlikes message
  • This creates a message and a like message.
  • The like message is removed when the unlike message arrives.
  • Removed rows leave gaps in ROWID; the row ID is not reused.
  • The database keeps the latest tapback state, not the full tapback history.

Technical detail

The index specified by the prefix maps to the index of the body part given by Message::parse_body().

• bp: GUID prefix for bubble message tapbacks (url previews, apps, etc).
• p:0/ GUID prefix for normal messages (body text, attachments).

If a message has 3 attachments followed by some text:

• 0 is the first image
• 1 is the second image
• 2 is the third image
• 3 is the text of the message

In this example, a Like on p:2/ is a like on the third image.

impl<'a> Eq for Tapback<'a>

impl<'a> PartialEq for Tapback<'a>

fn eq(&self, other: &Tapback<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
