Struct Mapping 

pub struct Mapping {
    pub dims: Vec<usize>,
    pub positions: Positions,
    pub frame: Frame,
    pub cell: CellConvention,
    pub provenance: String,
}

Positions for a subset of a domain’s dims, and the frame they are in.

Fields

dims: Vec<usize>

Indices into the domain’s dims, in the order positions expects. For Positions::Affine this is [row_dim, col_dim].

positions: Positions

frame: Frame

cell: CellConvention

provenance: String

Where this mapping came from: "stored" for what a reader found, or the name of the step that derived it (such as "normalise").

Implementations

impl Mapping

pub fn new(dims: Vec<usize>, positions: Positions, frame: Frame) -> Self

pub fn with_cell(self, cell: CellConvention) -> Self

pub fn with_provenance(self, provenance: impl Into<String>) -> Self

pub fn rung(&self) -> Rung

pub fn position(&self, index: &[f64]) -> Option<Vec<f64>>

The position at a continuous index, one value per covered dim in self.dims order (see the crate docs for the index convention). Returns one value per output coordinate, or None where the mapping cannot place the index (R0, outside a curvilinear grid, or a rung not evaluated in S1).

Trait Implementations

impl Clone for Mapping

fn clone(&self) -> Mapping

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mapping

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

Formats the value using the given formatter.
