CssiSpaceWeather

Available on crate feature alloc only.

pub struct CssiSpaceWeather

Space weather provider backed by CSSI historical data.

Looks up the correct daily record for a given epoch using binary search, then computes the NRLMSISE-00 7-element ap history array from the 3-hourly ap values across day boundaries.

Methods

fetch()

fn fetch(max_age: [Option<Duration>](https://doc.rust-lang.org/std/option/enum.Option.html)) -> [Result<Self, [Box<dyn std::error::Error>](https://doc.rust-lang.org/std/boxed/struct.Box.html)>](https://doc.rust-lang.org/std/result/enum.Result.html)

Fetch space weather data from CelesTrak with local caching.

Downloads SW-Last5Years.txt and caches it at ~/.cache/orts/SW-Last5Years.txt. If the cache file exists and is newer than max_age, it is reused. Pass None for the default max age of 24 hours.

fetch_default()

fn fetch_default() -> [Result<Self, [Box<dyn std::error::Error>](https://doc.rust-lang.org/std/boxed/struct.Box.html)>](https://doc.rust-lang.org/std/result/enum.Result.html)

Fetch with default settings (24-hour cache).

new()

fn new(data: CssiData) -> Self

Create a provider from parsed CSSI data.

from_file()

fn from_file(path: &std::path::Path) -> [Result<Self, [Box<dyn std::error::Error>](https://doc.rust-lang.org/std/boxed/struct.Box.html)>](https://doc.rust-lang.org/std/result/enum.Result.html)

Create a provider by parsing a CSSI file from a path.

with_out_of_range()

fn with_out_of_range(self, behavior: OutOfRangeBehavior) -> Self

Set out-of-range behavior (builder pattern).

data()

fn data(&self) -> &CssiData

Access the underlying data.

into_data()

fn into_data(self) -> CssiData

Consume the provider and return the inner data.

If other references to the data exist (via Clone), returns a clone.
