研究方向

Start by reviewing ndarray's existing stack functionality and the proposed from_rows and from_columns iterator APIs in this issue. Resolve whether collecting rows or columns and using stack is sufficient; done means the design is decided and, if new functionality is warranted, both construction paths have appropriate coverage.

描述

enhancement

A couple different times I have wanted to construct a 2D array from an iterator of 1D arrays. Is this something that should be added to ndarray?

Roughly, I'm thinking of a function from_rows<I: Iterator<Item=Array1>>(rows: I) -> Array2 and an analogous from_columns.

One design question that I'm not currently sure about is whether the user should have to specify any information about the dimensions. I am leaning towards "no," especially because it may be difficult to know the size of an iterator beforehand.

Possibly, it would make more sense to collect my iterator and use stack rather than adding new functionality. However, if this sounds useful, I would be happy to take a whack at implementing it.
