Struct FrameColumns 

pub struct FrameColumns<'a> { /* private fields */ }

Borrowed per-frame columns: coordinates and per-atom scalars.

Every accessor returns a slice of the model’s own AtomicConformation storage; nothing is copied. The borrow checker keeps the model alive and unmodified for 'a. Pointers handed across FFI from these slices carry the same rule, unenforced: they are valid until the model is dropped or its conformation is mutated.

Implementations

impl<'a> FrameColumns<'a>

pub fn new(model: &'a Model) -> Result<Self, BoundaryError>

Borrow the per-frame columns of model, validating their lengths.

Prefer TopologyColumns::frame, which also checks that the frame belongs to a given topology snapshot.

pub fn n_atoms(&self) -> u32

Number of atoms.

pub fn x(&self) -> &'a [f32]

X coordinates (Å).

pub fn y(&self) -> &'a [f32]

Y coordinates (Å).

pub fn z(&self) -> &'a [f32]

Z coordinates (Å).

pub fn occupancy(&self) -> Option<&'a [f32]>

Occupancy, if recorded.

pub fn b_iso(&self) -> Option<&'a [f32]>

Isotropic B-factor, if recorded.

pub fn confidence(&self) -> Option<&'a [f32]>

Per-atom confidence (e.g. pLDDT), if recorded.

pub fn columns(&self) -> Vec<Column<'a>>

Every present per-frame column by stable name. Absent optional columns are omitted.

pub fn positions(&self, layout: PositionLayout) -> GpuBuffer<'static>

Interleave x/y/z into one position buffer. Always an owned copy, since the model stores coordinates as separate SoA columns.

Trait Implementations

impl<'a> Clone for FrameColumns<'a>

fn clone(&self) -> FrameColumns<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Copy for FrameColumns<'a>

impl Debug for FrameColumns<'_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
