Struct smartnoise_runtime::proto::ToDataframe

pub struct ToDataframe {}

ToDataframe Component

Name columns of an array to produce a Dataframe with the specified names. Typically used when partitioning a dataframe with preprocessed columns.

This struct represents an abstract computation. Arguments are provided via the graph. Additional options are set via the fields on this struct. The return is the result of the to_dataframe on the arguments.

Arguments

• data - Array - ndarray (structured or homogeneous), Iterable, dict, or DataFrame
• names - Array - Column labels to use for resulting frame. Will default to RangeIndex (0, 1, 2, …, n) if no column labels are provided.

Returns

• Value - Dataframe - Dataframe in target language, for example pandas.DataFrame.

Trait Implementations
