Struct anise::structure::dataset::DataSet

pub struct DataSet<T: DataSetT, const ENTRIES: usize> {
    pub metadata: Metadata,
    pub lut: LookUpTable<ENTRIES>,
    pub data_checksum: u32,
    pub bytes: Bytes,
    /* private fields */
}

A DataSet is the core structure shared by all ANISE binary data.

Fields

metadata: Metadata

lut: LookUpTable<ENTRIES>

All datasets have LookUpTable (LUT) that stores the mapping between a key and its index in the ephemeris list.

data_checksum: u32

bytes: Bytes

The actual data from the dataset

Implementations

impl DataSet<PlanetaryData, MAX_PLANETARY_DATA>

pub fn describe(&self) -> String

Returns a table describing this planetary data set

impl<T: DataSetT, const ENTRIES: usize> DataSet<T, ENTRIES>

pub fn try_from_bytes<B: Deref<Target = [u8]>>( bytes: B ) -> Result<Self, DataSetError>

Try to load an Anise file from a pointer of bytes

pub fn from_bytes<B: Deref<Target = [u8]>>(buf: B) -> Self

Forces to load an Anise file from a pointer of bytes. Panics if the bytes cannot be interpreted as an Anise file.

pub fn crc32(&self) -> u32

Compute the CRC32 of the underlying bytes

pub fn set_crc32(&mut self)

Sets the checksum of this data.

pub fn check_integrity(&self) -> Result<(), IntegrityError>

pub fn scrub(&self) -> Result<(), IntegrityError>

Scrubs the data by computing the CRC32 of the bytes and making sure that it still matches the previously known hash

pub fn get_by_id(&self, id: i32) -> Result<T, DataSetError>

pub fn get_by_name(&self, name: &str) -> Result<T, DataSetError>

pub fn save_as( &self, filename: &PathBuf, overwrite: bool ) -> Result<(), DataSetError>

Saves this dataset to the provided file If overwrite is set to false, and the filename already exists, this function will return an error.

pub fn len(&self) -> usize

Returns the length of the LONGEST of the two look up tables

pub fn is_empty(&self) -> bool

Returns whether this dataset is empty

Trait Implementations

impl<T: Clone + DataSetT, const ENTRIES: usize> Clone for DataSet<T, ENTRIES>

fn clone(&self) -> DataSet<T, ENTRIES>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + DataSetT, const ENTRIES: usize> Debug for DataSet<T, ENTRIES>

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

Formats the value using the given formatter.

impl<'a, T: DataSetT, const ENTRIES: usize> Decode<'a> for DataSet<T, ENTRIES>

fn decode<D: Reader<'a>>(decoder: &mut D) -> Result<Self>

Attempt to decode this message using the provided decoder.

fn from_der(bytes: &'a [u8]) -> Result<Self, Error>

Parse Self from the provided DER-encoded byte slice.

impl<T: Default + DataSetT, const ENTRIES: usize> Default for DataSet<T, ENTRIES>

fn default() -> DataSet<T, ENTRIES>

Returns the “default value” for a type.

impl<T: DataSetT, const ENTRIES: usize> Display for DataSet<T, ENTRIES>

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

Formats the value using the given formatter.

impl<T: DataSetT, const ENTRIES: usize> Encode for DataSet<T, ENTRIES>

fn encoded_len(&self) -> Result<Length>

Compute the length of this value in bytes when encoded as ASN.1 DER.

fn encode(&self, encoder: &mut impl Writer) -> Result<()>

Encode this value as ASN.1 DER using the provided Writer.

fn encode_to_slice<'a>(&self, buf: &'a mut [u8]) -> Result<&'a [u8], Error>

Encode this value to the provided byte slice, returning a sub-slice containing the encoded message.

fn encode_to_vec(&self, buf: &mut Vec<u8>) -> Result<Length, Error>

Encode this message as ASN.1 DER, appending it to the provided byte vector.

fn to_der(&self) -> Result<Vec<u8>, Error>

Encode this type as DER, returning a byte vector.

impl<T: PartialEq + DataSetT, const ENTRIES: usize> PartialEq for DataSet<T, ENTRIES>

fn eq(&self, other: &DataSet<T, ENTRIES>) -> 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.
