Enum MultiAngleMode 

pub enum MultiAngleMode {
    Error,
    Sum,
    SelectAngle(usize),
}

Policy for handling multi-angle NeXus histogram files.

Issue #430: the loader must refuse to silently collapse the rotation-angle dimension. Callers choose explicitly which projection (or combination of projections) they want.

Variants

Error

Reject files with more than one rotation angle with a clear IoError::InvalidParameter. Single-angle files (n_rot == 1) load normally. This is the default — it prevents silent data loss for callers that aren’t multi-angle-aware.

Sum

Sum across all rotation angles into a single (tof, y, x) volume. This is the legacy auto-sum behaviour, preserved as an explicit opt-in so that callers can’t invoke it by accident. Multi-angle analysis information is irreversibly lost on this path.

SelectAngle(usize)

Extract a single rotation angle by index. Returns an error if the index is out of range.

Trait Implementations

impl Clone for MultiAngleMode

fn clone(&self) -> MultiAngleMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MultiAngleMode

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

Formats the value using the given formatter.

impl Default for MultiAngleMode

fn default() -> MultiAngleMode

Returns the “default value” for a type.

impl PartialEq for MultiAngleMode

fn eq(&self, other: &MultiAngleMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
