CssiData

Available on crate feature alloc only.

pub struct CssiData

Parsed CSSI space weather data.

Non-empty, at most one record per calendar day, ascending by date. Days may be missing: a hand-trimmed file (like this repository’s own test fixture) covers a few disjoint intervals, so CssiSpaceWeather resolves the 3-hour Ap history and the previous day’s F10.7 by calendar date rather than by array position. Every constructor, including CssiData::truncate_after, goes through CssiData::from_records.

Methods

parse()

fn parse(text: &str) -> [Result<Self, CssiParseError>](https://doc.rust-lang.org/std/result/enum.Result.html)

Parse CSSI space weather data from text content.

Accepts the full content of SW-Last5Years.txt or SW-All.txt. Parses OBSERVED and DAILY_PREDICTED sections. Records are sorted by date after parsing; duplicates from overlapping sections are resolved in favor of OBSERVED data.

len()

fn len(&self) -> usize

Number of daily records.

is_empty()

fn is_empty(&self) -> bool

Whether the dataset is empty.

date_range()

fn date_range(&self) -> [Option<(Epoch, Epoch)>](https://doc.rust-lang.org/std/option/enum.Option.html)

Date range as (first_epoch, last_epoch).

records()

fn records(&self) -> &[CssiDailyRecord]

Access the underlying records.

truncate_after()

fn truncate_after(&self, epoch: &Epoch) -> [Result<Self, CssiParseError>](https://doc.rust-lang.org/std/result/enum.Result.html)

Return a new CssiData containing only records up to (and including) the given epoch’s calendar day.

Useful for simulating “what data was available at time T” by discarding future observations. When used with CssiSpaceWeather in Clamp mode, queries after the cutoff will repeat the last available day’s values.

Returns CssiParseError::NoData when the cutoff precedes the whole dataset: an empty dataset would make every subsequent query panic, so it is not representable as a CssiData.
