Struct RuleMeta 

#[non_exhaustive]
pub struct RuleMeta {
    pub id: &'static str,
    pub default_severity: Severity,
    pub description: &'static str,
    pub source: RuleSource,
}

Metadata about a single rule, as exposed by the public catalog.

Marked #[non_exhaustive] so that adding fields in future minor releases does not break downstream code that reads (but never constructs) RuleMeta.

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.

id: &'static str

default_severity: Severity

description: &'static str

source: RuleSource

The external standard this rule is derived from.

Implementations

impl RuleMeta

pub fn revenue_impact(&self) -> bool

Returns true when violating this rule has a direct revenue or measurement impact — lost impressions, broken tracking, zero fill.

This covers both rules whose source is RuleSource::IndustryBestPractice and rules whose source is an IAB spec standard but whose real-world consequence is measurable revenue loss (missing <Impression>, dead wrapper redirect, etc.).
