Struct ClassRule 

#[non_exhaustive]
pub struct ClassRule {
    pub name: String,
    pub matcher: Matcher,
    pub bucket: String,
    pub priority: u8,
    pub weight: u16,
}

A matcher plus what to do with what it matches.

#[non_exhaustive] with a Default — see the module doc for why the pairing is required rather than stylistic. The default is an unnamed class that claims every unit and names no bucket, so it is always edited before use; note that a defaulted weight of zero is rejected under Discipline::WeightedRoundRobin.

In the written form name and bucket are required and the other three default, because the two that are required are the two whose defaults are wrong rather than merely empty: an unnamed class collides with the next unnamed class as ShapeError::DuplicateClassName, and a class naming no bucket at all is ShapeError::UnknownBucket against the empty string. Both are refusals about a key the author never wrote.

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.

name: String

The class name. Unique across the profile, and the label under which this class’s statistics are reported.

matcher: Matcher

Which units this class claims.

bucket: String

The BucketConfig::name this class charges against. Several classes may share one bucket, which is what makes Discipline mean anything.

priority: u8

Discipline::StrictPriority orders classes by this; higher wins.

Distinct from MoQT’s publisher_priority, which Matcher::priority keys on: this one is the scheduler’s, and it is always present.

weight: u16

Discipline::WeightedRoundRobin shares a bucket by this. Zero is rejected under that discipline and ignored under the other two.
