Struct galileo_osnma::Gst

pub struct Gst { /* private fields */ }

GST (Galileo System Time)

The Galileo System Time, stored as a week number and a time of week.

Examples

use galileo_osnma::Gst;

let gst = Gst::new(1177, 175767);
assert_eq!(gst.wn(), 1177);
assert_eq!(gst.tow(), 175767);

Implementations

impl Gst

pub fn new(wn: Wn, tow: Tow) -> Self

Constructs a new GST from a week number and TOW.

Panics

Panics if tow is greater or equal to 604800 (the number of seconds in a week).

pub fn wn(&self) -> Wn

Returns the week number of the GST.

pub fn tow(&self) -> Tow

Returns the time of week of the GST.

pub fn add_seconds(&self, seconds: i32) -> Self

Adds seconds seconds to the GST.

The GST corresponding to the sum is returned.

Examples

use galileo_osnma::Gst;

let gst = Gst::new(1177, 175767);
let gst_next_page = gst.add_seconds(2);
assert_eq!(gst_next_page.wn(), 1177);
assert_eq!(gst_next_page.tow(), 175769);

assert_eq!(gst_next_page.add_seconds(-2), gst);

pub fn add_subframes(&self, subframes: i32) -> Self

Adds subframes 30-second subframes to the GST.

The GST corresponding to the sum is returned.

Examples

use galileo_osnma::Gst;

let gst = Gst::new(1177, 175767);
let gst2 = gst.add_subframes(3);
assert_eq!(gst2.wn(), 1177);
assert_eq!(gst2.tow(), 175857);

assert_eq!(gst2.add_subframes(-3), gst);

pub fn gst_subframe(&self) -> Self

Returns the GST at the start of the subframe that contains self.

The GST returned has the same week number as self and its time of week is the largest multiple of 30 seconds that is smaller or equal than the time of week of self.

Examples

use galileo_osnma::Gst;

let gst = Gst::new(1177, 175767);
let subframe = gst.gst_subframe();
assert_eq!(subframe.wn(), 1177);
assert_eq!(subframe.tow(), 175740);

pub fn is_subframe(&self) -> bool

Returns true if self corresponds to the start of a subframe.

A GST corresponds to the start of a subframe if its time of week is a multiple of 30 seconds.

Examples

use galileo_osnma::Gst;

let gst = Gst::new(1177, 175767);
let subframe = gst.gst_subframe();
assert_eq!(gst.is_subframe(), false);
assert_eq!(subframe.is_subframe(), true);

pub fn subframes_difference(&self, other: Gst) -> i32

Returns the difference in subframes between other and self.

The returned value is equal to the number of GST seconds elapsed between self and other, divided by 30.

Trait Implementations

impl Clone for Gst

fn clone(&self) -> Gst

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Gst

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

Formats the value using the given formatter.

impl Hash for Gst

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Gst

fn cmp(&self, other: &Gst) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Gst

fn eq(&self, other: &Gst) -> 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 PartialOrd for Gst

fn partial_cmp(&self, other: &Gst) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
