Struct ProductIdentity 

pub struct ProductIdentity {

    pub family: ProductType,
    pub analysis_center: AnalysisCenter,
    pub publisher: ProductPublisher,
    pub solution: SolutionClass,
    pub campaign: ProductCampaign,
    pub version: u8,
    pub date: ProductDate,
    pub issue: Option<String>,
    pub span: String,
    pub sample: String,
    pub official_filename: String,
    pub format: ProductFormat,
    pub format_version: Option<String>,
    pub prediction_horizon_days: Option<u8>,
}

Exact identity of one public GNSS product, independent of distributor.

The official filename is part of the identity. Transport compression and URL belong to DistributionLocation because two distributors may package the same decompressed product differently.

Fields

family: ProductType

Product family.

analysis_center: AnalysisCenter

Catalog analysis-center product line.

publisher: ProductPublisher

Producing or combining organization.

solution: SolutionClass

Solution class or tier.

campaign: ProductCampaign

Campaign or project.

version: u8

Product-line version encoded by the long filename.

date: ProductDate

Nominal product start date.

issue: Option<String>

Optional HHMM issue/start time.

span: String

Intended coverage period token, for example 01D.

sample: String

Sampling interval token, for example 05M.

official_filename: String

Official filename without transport compression suffix.

format: ProductFormat

Public serialization format.

format_version: Option<String>

Parsed serialization revision when the request constrains one.

Catalog identities leave this unset because the revision is carried by product content rather than the official filename. A resolved identity may set it after parsing the product.

prediction_horizon_days: Option<u8>

Prediction horizon when the product line encodes one.

Implementations

impl ProductIdentity

pub fn validate(&self) -> Result<(), DataCatalogError>

Validate that every identity field agrees with the official filename.

This is required for caller-constructed values before using them in a request, URL, or cache path. Catalog-produced identities are validated before they are returned.

pub fn key(&self) -> Result<String, DataCatalogError>

Deterministic identity key suitable for a portable cache layout.

pub fn canonical_bytes(&self) -> Result<Vec<u8>, DataCatalogError>

Canonical, unambiguous bytes containing every exact identity field.

The encoding is ASCII/UTF-8 field text separated by NUL bytes. It is a stable cross-interface input to cache identity hashing, not a display or interchange document.

pub fn cache_relpath( &self, source: DistributionSource, ) -> Result<String, DataCatalogError>

Deterministic cache path for this identity and distributor.

Trait Implementations

impl Clone for ProductIdentity

fn clone(&self) -> ProductIdentity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProductIdentity

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

Formats the value using the given formatter.

impl Eq for ProductIdentity

impl Hash for ProductIdentity

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 PartialEq for ProductIdentity

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

Equality operator ==.

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

Inequality operator !=.
