Struct EventTypeBuilder 

pub struct EventTypeBuilder { /* private fields */ }

Implementations

impl EventTypeBuilder

pub fn define_record(self) -> EventTypeRecordBuilder

Starts building a record-shaped event type with named fields.

pub fn default_event_type(self, tpe: Type) -> Self

Sets the default event type used when no data source-specific type is found.

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

Registers a type for a specific named data source.

Queries targeting data_source will use tpe for type checking instead of the default event type. Data source names are case-insensitive.

pub fn custom(self, name: &str) -> Self

Declares a custom type by name.

pub fn custom_default_event_type(self, name: &str) -> Self

Declares a custom event type by name for as default event type.

pub fn custom_for_data_source(self, name: &str, data_source: &str) -> Self

Declares a custom event type by name for a data source.

pub fn done(self) -> SessionBuilder

Finalizes type configuration and returns the SessionBuilder.
