Struct SubjectPattern 

pub struct SubjectPattern { /* private fields */ }

A Subject that may contain wildcards. Used for subscriptions and cache invalidation patterns, never as a concrete Message.subject.

Implementations

impl SubjectPattern

pub fn from_str(s: &str) -> Result<Self, SubjectError>

Parse a SubjectPattern from a dot-joined string.

Errors

Returns SubjectError::WildcardMultiNotLast if # appears before the last segment. Other grammar errors mirror Subject::from_str.

pub fn matches(&self, subject: &Subject) -> bool

Test whether this pattern matches a concrete subject.

• Concrete matches by exact string equality;
• WildcardOne (+) matches any single segment;
• WildcardMulti (#) matches zero or more trailing segments.

pub fn as_str(&self) -> String

Dot-joined string form.

pub fn segments(&self) -> &[PatternSegment]

The pattern segments.
