Method copy_from_slice

src/buffer.rs:531–533

Copies the specified slice into the buffer. If the buffer is multi-dimensional, the elements in the slice are expected to be in C-style order. Fails if the buffer is read-only. Fails if the slice does not have the correct length (`buf.item_count()`). Fails if the buffer format is not compatible with type `T`. To check whether the buffer format is compatible before calling this method, use `<T as

(&self, py: Python, source: &[T])

    /// use `<T as buffer::Element>::is_compatible_format(buf.format())`.
    /// Alternatively, `match buffer::ElementType::from_format(buf.format())`.
    pub fn copy_from_slice<T: Element + Copy>(&self, py: Python, source: &[T]) -> PyResult<()> {
        self.copy_from_slice_impl(py, source, b'C')
    }

    /// Copies the specified slice into the buffer.
    /// If the buffer is multi-dimensional, the elements in the slice are expected to be in Fortran-style order.
