Expand description

Modes of communication between the Rust Geodesy internals and the external world (i.e. resources like grids, transformation definitions, or ellipsoid parameters).

Required Methods§

source

fn new() -> Self
where Self: Sized,

In general, implementations should make sure that new differs from default only by adding access to the builtin adaptors (geo:in, gis:out etc.)
