Struct PreambleInfo 

pub struct PreambleInfo {
    pub count: u64,
    pub collected_over_s: f64,
    pub selectors: Vec<String>,
    pub semantics: PreambleSemantics,
    pub incomplete: u64,
    pub failed: Vec<String>,
}

The state preamble’s account of itself (RFC 13 §4.1, version 2).

Fields

count: u64

Preamble rows written — counted apart from observed rows (O6).

collected_over_s: f64

How long the fan-in GET took: a preamble is collected over a span, never at an instant (RFC 13 §4.4’s obligation, inherited).

selectors: Vec<String>

The selectors actually fetched — the state-class projection of the watched set, so a watch that reaches no state key fetched nothing.

semantics: PreambleSemantics

incomplete: u64

Replies the bounded fetch could not keep or could not read: error envelopes plus replies elided past the reply bound (O6).

failed: Vec<String>

Watched selectors whose state could not be fetched at all — a GET that could not be issued, or a selector that reaches no state key — named rather than folded into a count (O5).
