Enum TmercAlgo 

#[non_exhaustive]
pub enum TmercAlgo {
    Auto,
    EvendenSnyder,
    PoderEngsager,
}

Algorithm selection for transverse Mercator, mirroring PROJ’s tmerc algo choice.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Auto

Pick automatically. AUTO defaults to TmercAlgo::PoderEngsager for ellipsoidal tmerc here, matching PROJ’s preference for the exact series.

EvendenSnyder

Evenden/Snyder approximate series (PROJ approx).

PoderEngsager

Poder/Engsager exact series (PROJ exact, the default for ellipsoids).
