Struct gds::GdsUnits

pub struct GdsUnits(/* private fields */);

An encoding of GDS units.

Each GDSII Library has two length-units, referred to as “DB Units” and “User Units” respectively. Essentially all spatial data throughout the Library is denoted in “DB Units”. “User units” are a sort of recommendation for GUI programs to use when displaying the Library.

From the spec’s UNITS record-description:

Contains two eight-byte real numbers.
The first number is the size of a database-unit, in user-units.
The second is the size of a database-unit in meters.
To calculate the size of a user-unit in meters, divide the second number by the first.

These two numbers are stored as-is in the GdsUnits tuple-struct.

Implementations

impl GdsUnits

pub fn new(num1: f64, num2: f64) -> Self

Creates a new GdsUnits

pub fn db_unit(&self) -> f64

Gets the database-unit size in meters. Used for all spatial data.

pub fn user_unit(&self) -> f64

Gets the user-unit size in meters. Largely for display/debug.

Trait Implementations

impl Clone for GdsUnits

fn clone(&self) -> GdsUnits

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GdsUnits

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

Formats the value using the given formatter.

impl Default for GdsUnits

fn default() -> Self

Default values for GDS units:

• DB-Unit = 1nm
• User-Unit = 1µm (1000x the DB-Unit)

impl<'de> Deserialize<'de> for GdsUnits

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for GdsUnits

fn eq(&self, other: &GdsUnits) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for GdsUnits

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
