Expand description
Define capacities of child data or data buffers.
Variants§
Binary(usize, Option<usize>)
Binary, Utf8 and LargeUtf8 data types Define
- the capacity of the array offsets
- the capacity of the binary/ str buffer
List(usize, Option<Box<Capacities>>)
List and LargeList data types Define
- the capacity of the array offsets
- the capacity of the child data
Struct(usize, Option<Vec<Capacities>>)
Struct type
- the capacity of the array
- the capacities of the fields
Dictionary(usize, Option<Box<Capacities>>)
Dictionary type
- the capacity of the array/keys
- the capacity of the values
Array(usize)
Don’t preallocate inner buffers and rely on array growth strategy
