Struct GroupTypeBuilder

pub struct GroupTypeBuilder<'a> {
    name: &'a str,
    repetition: Option<Repetition>,
    converted_type: ConvertedType,
    logical_type: Option<LogicalType>,
    fields: Vec<TypePtr>,
    id: Option<i32>,
}

A builder for group types. All attributes are optional except the name. Note that if not specified explicitly, None is used as the repetition of the group, which means it is a root (message) type.

Fields

name: &'a str

repetition: Option<Repetition>

converted_type: ConvertedType

logical_type: Option<LogicalType>

fields: Vec<TypePtr>

id: Option<i32>
