Enum ColumnData 

pub enum ColumnData<'a> {
    U8(&'a [u8]),
    I8(&'a [i8]),
    U32(&'a [u32]),
    I32(&'a [i32]),
    F32(&'a [f32]),
}

A borrowed, contiguous, typed numeric column.

Every variant borrows storage owned elsewhere — a Model’s conformation, its AtomicHierarchy, or a TopologyColumns snapshot — so creating one never copies.

Variants

U8(&'a [u8])

I8(&'a [i8])

U32(&'a [u32])

I32(&'a [i32])

F32(&'a [f32])

Implementations

impl<'a> ColumnData<'a>

pub fn scalar_type(&self) -> ScalarType

Element type of the column.

pub fn len(&self) -> usize

Number of scalars (rows).

pub fn is_empty(&self) -> bool

Returns true if the column has no rows.

pub fn byte_len(&self) -> usize

Size of the column in bytes.

pub fn as_ptr(&self) -> *const u8

Pointer to the first scalar, for FFI hand-off together with Self::len.

The pointer is valid exactly as long as the borrow 'a.

pub fn le_bytes(&self) -> Cow<'a, [u8]>

Little-endian bytes of the column; zero-copy on little-endian targets.
