Struct EventTypeRecordBuilder 

pub struct EventTypeRecordBuilder { /* private fields */ }

Builder for defining the fields of a record-shaped event type.

Obtained by calling EventTypeBuilder::define_record. Add fields with prop and finalize with as_default_event_type or for_data_source to return to the EventTypeBuilder.

Implementations

impl EventTypeRecordBuilder

pub fn prop_when(self, test: bool, name: &str, tpe: Type) -> Self

Conditionally adds a field to the event record type.

pub fn prop(self, name: &str, tpe: Type) -> Self

Adds a field with the given name and type to the event record type.

pub fn prop_with_custom_when(self, test: bool, name: &str, tpe: &str) -> Self

Conditionally adds a field with a custom type to the event record type.

pub fn as_default_event_type(self) -> EventTypeBuilder

Finalizes the event record type and returns the SessionBuilder.

pub fn for_data_source(self, data_source: &str) -> EventTypeBuilder

Finalizes the record type and registers it for a specific named data source.

Queries targeting data_source will use this record type for type checking. Data source names are case-insensitive. Returns the EventTypeBuilder to allow chaining further type declarations.
