Struct SubjectBuilder 

Source 
pub struct SubjectBuilder { /* private fields */ }
Expand description

Fluent builder for constructing Subject values.

Created via Subject::build(identity). Chain .label() and .property() calls, then finalize with .done() or use Into<Subject>.

Implementations§

Source§

impl SubjectBuilder

Source

pub fn label(self, label: impl Into<String>) -> Self

Adds a label to the subject being built.

Source

pub fn property(self, key: impl Into<String>, value: impl Into<Value>) -> Self

Adds a property to the subject being built.

Source

pub fn done(self) -> Subject

Finalizes the builder and returns the constructed Subject.
