Struct BudgetDecl 

#[non_exhaustive]
pub struct BudgetDecl {
    pub rss_mb: Option<i64>,
    pub tables: Vec<TableBudget>,
}

The [budget] table of a served registry slice (RFC 08 §2, v1.32): what this producer may cost the machine it runs on, in the units its health document’s self_stats reports (RFC 04 §1.2).

The first per-producer table on the slice that is not a subject, procedure, tier or stream: it generates no key and no builder, and rides the slice verbatim into introspect (RFC 08 §6) so an observer that can read self_stats can say whether the claim holds (RFC 13 §3). Every bound is optional here for the same reason every other optional column is — this type reads foreign slices, and the strict lint belongs to that build’s own zenkey-build. #[non_exhaustive]: every version of this type so far has been the previous one plus a field (encoding v1.5, blob v1.8, media v1.16), and each of those was a breaking change for anyone constructing one. It is a parse result, not a thing callers build — parse_slice is the constructor — so the attribute costs the intended use nothing and stops the next field being a break (#325).

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.

rss_mb: Option<i64>

The whole process’s resident set, in MiB (rss_mb).

tables: Vec<TableBudget>

Each bounded structure the producer keeps ([[budget.tables]]).

Implementations

impl BudgetDecl

pub fn new() -> Self
