Implementations

impl EventClass

Represents a class of tracepoints. Every tracepoint of the same class shares the same set of fields. You can have as many tracepoints of the same class as you like, but tracepoint names are namespaced per provider, not per-class.

pub fn add_field<S: Into<String>>( &mut self, field_name: S, ty: CTFType, ) -> &mut Self

Adds a new field to the tracepoint. See the module level documentation for examples.

pub fn instantiate<S: Into<String>>(&mut self, instance_name: S) -> &mut Self

Instantiate the class, creating a new tracepoint. See the module level documentation for examples.

pub fn instantiate_with_level<S: Into<String>>( &mut self, instance_name: S, level: LogLevel, ) -> &mut Self

Instantiate the class, creating a new tracepoint. Also allows specification of the level
