Struct XdbcTypeInfoData

Source 
pub struct XdbcTypeInfoData {
    batch: RecordBatch,
}
Expand description

Helper to create CommandGetXdbcTypeInfo responses.

CommandGetXdbcTypeInfo are metadata requests used by a Flight SQL server to communicate supported capabilities to Flight SQL clients.

Servers constuct - usually static - XdbcTypeInfoData via the XdbcTypeInfoDataBuilder, and build responses using CommandGetXdbcTypeInfo::into_builder.

Fields§

§batch: RecordBatch
