Struct LinearUnit 

pub struct LinearUnit { /* private fields */ }

A coordinate system’s projected linear unit.

The stored value is the conversion factor from one native unit to meters.

Implementations

impl LinearUnit

pub const fn metre() -> Self

Metre-based projected coordinates.

pub const fn meter() -> Self

Alias for LinearUnit::metre.

pub const fn kilometre() -> Self

Kilometer-based projected coordinates.

pub const fn kilometer() -> Self

Alias for LinearUnit::kilometre.

pub const fn foot() -> Self

International foot-based projected coordinates.

pub const fn us_survey_foot() -> Self

US survey foot-based projected coordinates.

pub fn from_meters_per_unit(meters_per_unit: f64) -> Result<Self>

Construct a custom projected linear unit from its meter conversion factor.

pub const fn meters_per_unit(self) -> f64

Return the number of meters represented by one native projected unit.

pub const fn to_meters(self, value: f64) -> f64

Convert a native projected coordinate value into meters.

pub const fn from_meters(self, value: f64) -> f64

Convert a meter value into the native projected unit.

Trait Implementations

impl Clone for LinearUnit

fn clone(&self) -> LinearUnit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LinearUnit

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

Formats the value using the given formatter.

impl PartialEq for LinearUnit

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