Enum Dao 

pub enum Dao {
    HumanReadable {
        lat_digit: u8,
        lon_digit: u8,
    },
    Base91 {
        lat_offset: u8,
        lon_offset: u8,
    },
}

DAO (Datum Ambiguity Override) precision extension parsed from the comment field.

When present, DAO provides sub-hundredth-of-a-minute precision beyond what the standard DDmm.mm format can encode. The offsets are applied to lat/lon at parse time so callers always receive refined coordinates.

Variants

HumanReadable

Human-readable form !WXY!: X and Y are decimal digits 0–9 encoding an extra digit of minute resolution (thousandths of a minute ≈ 1.85 m).

Fields

lat_digit: u8

lon_digit: u8

Base91

Base-91 form !wxy!: two base-91 characters encoding the sub-hundredth position within the current cell (≈ 0.2 m resolution).

Fields

lat_offset: u8

lon_offset: u8

Implementations

impl Dao

pub fn offsets_degrees(&self) -> (f64, f64)

Latitude and longitude adjustments in degrees that refine the base position. These are always non-negative; the caller applies them in the direction of the base coordinate’s sign.

Trait Implementations

impl Clone for Dao

fn clone(&self) -> Dao

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Dao

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

Formats the value using the given formatter.

impl PartialEq for Dao

fn eq(&self, other: &Dao) -> 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.
