Macro inspect 

inspect!() { /* proc-macro */ }

Captures a snapshot of any value that implements Debug and sends it to the lupa inspector (web UI and/or TUI).

The macro evaluates the expression, takes its {:#?} debug representation, and records it along with the source location and the expression itself as a label. The snapshot becomes visible in the inspector’s “Snapshots” tab.

Return value

The macro returns the original value (by reference) so it can be used inline, similar to dbg!.

Example

let user = User::new("Alice");
inspect!(user);   // snapshot appears in lupa

Feature flags

When the web feature is enabled (default), the snapshot is also broadcast over WebSocket to all connected browser clients.
