Struct SubjectPattern 

pub struct SubjectPattern { /* private fields */ }

A parsed registry subject pattern.

Implementations

impl SubjectPattern

pub fn parse(pattern: &str) -> Result<Self, PatternError>

Parse a registry pattern (flow/red/{quantile}, {device}/{metric...}).

Same lexical rules as zenkey-build’s registry linter, minus the reserved-leaf checks (this type also parses patterns served by a foreign fleet, where local reservations do not apply).

pub fn chunks(&self) -> &[PatternChunk]

The pattern’s positions.

pub fn as_str(&self) -> &str

The pattern text as written.

pub fn matches(&self, tail: &[&str]) -> Option<Vec<(&str, String)>>

Match a concrete subject tail, binding named variables. A rest variable binds the remaining chunks joined with /.

pub fn precedence(&self) -> (Vec<u8>, &str)

The parse-precedence key: per-position ranks (literal < var < rest), compared lexicographically, ties broken by pattern text — exactly the order the generated parse arms are emitted in.

pub fn selector_tail(&self) -> String

The selector tail for this family: {var} → *, {var...} → **.

pub fn ke_format_spec(&self) -> Option<String>

The zenoh KeFormat spec for this pattern (${var:*} fields), when the pattern is expressible in that engine: rest variables are not (KeFormat’s ** matches zero chunks; {var...} requires one or more), so they return None and the hand matcher stays normative.
