Struct ListType

Source 
pub struct ListType {
    pub element_field: NestedFieldRef,
}
Expand description

A list is a collection of values with some element type. The element field has an integer id that is unique in the table schema. Elements can be either optional or required. Element types may be any type.

Fields§

§element_field: NestedFieldRef

Element field of list type.
