Examples

Create an instance of bool8 extension type:

>>>importpyarrowaspa>>>type=pa.bool8()>>>typeBool8Type(extension<arrow.bool8>)

Inspect the data type:

>>>type.storage_typeDataType(int8)

Create a table with a bool8 array:

>>>arr=[-1,0,1,2,None]>>>storage=pa.array(arr,pa.int8())>>>other=pa.ExtensionArray.from_storage(type,storage)>>>pa.table([other],names=["unknown_col"])pyarrow.Tableunknown_col: extension<arrow.bool8>----unknown_col: [[-1,0,1,2,null]]
