Struct RandomGroups 

pub struct RandomGroups {
    pub parameter_names: Vec<String>,
    pub group_shape: Vec<usize>,
    pub gcount: usize,
    pub pcount: usize,
    pub bitpix: Bitpix,
    /* private fields */
}

A decoded random-groups primary array.

Fields

parameter_names: Vec<String>

PTYPEn parameter names, in order (length pcount).

group_shape: Vec<usize>

The per-group array shape (NAXIS2..NAXISm; the NAXIS1 zero sentinel is dropped).

gcount: usize

pcount: usize

bitpix: Bitpix

Implementations

impl RandomGroups

pub fn array_len(&self) -> usize

Elements in one group’s array — Π NAXIS2..NAXISm, the FITS Eq. 2 product. With no array axis (NAXIS = 1) this is the empty product 1, not 0, matching how [crate::hdu]’s data_extent sizes the group (one array element per group); shape_product’s image-specific “empty ⇒ 0” rule must not be used here, or the two disagree and a NAXIS = 1 group fails the size check.

pub fn parameters_physical(&self, group: usize) -> Vec<f64>

The physical parameter values of group g: PZEROn + PSCALn × raw.

pub fn parameter_physical(&self, group: usize, name: &str) -> Option<f64>

The physical value of the named group parameter (§6.3): when extra precision splits one logical parameter into two or more group parameters sharing a PTYPEn name, the value is the sum of those addends’ physical values. None if no parameter has the name. (For the raw per-addend values, use RandomGroups::parameters_physical.)

pub fn array_physical(&self, group: usize) -> Vec<f64>

The physical array values of group g: BZERO + BSCALE × raw.

Trait Implementations
