Struct PerfAnswer 

#[non_exhaustive]
pub struct PerfAnswer {
    pub records: Vec<FrameRecord>,
    pub next: u64,
    pub dropped: u64,
    pub measured: bool,
    pub frames: u32,
    pub snapshot: Option<HeapSnapshot>,
}

The frames’ records a Request::Perf asked for, counted as the contract’s PerfRead counts them.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

records: Vec<FrameRecord>

The kept records numbered since or more, oldest first, the first max of them.

next: u64

The number to read from next time: the one after the last record answered; 0 for a since past the ring’s next number.

dropped: u64

How many records numbered since or more the ring no longer keeps.

measured: bool

Whether any frame was measured.

frames: u32

The frames run: App::frame_number.

snapshot: Option<HeapSnapshot>

The heap snapshot taken after the frame, if one was asked for and the build takes one (a debug build that counts the heap by tag).
