Trait ndarray_npy::ReadableElement

pub trait ReadableElement: Sized {
    fn read_to_end_exact_vec<R: Read>(
        reader: R, 
        type_desc: &PyValue, 
        len: usize
    ) -> Result<Vec<Self>, ReadDataError>;
}

An array element type that can be read from an .npy or .npz file.

Required methods

fn read_to_end_exact_vec<R: Read>(
    reader: R,
    type_desc: &PyValue,
    len: usize
) -> Result<Vec<Self>, ReadDataError>

Reads to the end of the reader, creating a Vec of length len.

This method should return Err(_) in at least the following cases:

• if the type_desc does not match Self
• if the reader has fewer elements than len
• if the reader has extra bytes after reading len elements
