Struct EventTypeBuilder 

pub struct EventTypeBuilder<'a> { /* private fields */ }

Builder for configuring type information on a SessionBuilder.

Obtained by calling SessionBuilder::declare_type. Use define_record to define a record-shaped type. Call done to return to the SessionBuilder.

Implementations

impl<'a> EventTypeBuilder<'a>

pub fn define_record(self) -> EventTypeRecordBuilder<'a>

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

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 done(self)

Finalizes type configuration and returns the SessionBuilder.
