Struct oid_registry::OidRegistry

pub struct OidRegistry<'a> { /* private fields */ }

Registry of known OIDs

Use OidRegistry::default() to create an empty registry. If the corresponding features have been selected, the with_xxx() methods can be used to add sets of known objets to the database.

Example

use asn1_rs::{oid, Oid};
use oid_registry::{OidEntry, OidRegistry};

let mut registry = OidRegistry::default()
    .with_crypto() // only if the 'crypto' feature is enabled
;

// entries can be added by creating an OidEntry object:
let entry = OidEntry::new("shortName", "description");
registry.insert(oid!(1.2.3.4), entry);

// when using static strings, a tuple can also be used directly for the entry:
registry.insert(oid!(1.2.3.5), ("shortName", "A description"));

// To query an entry, use the `get` method:
const OID_1234: Oid<'static> = oid!(1.2.3.4);
let e = registry.get(&OID_1234);
assert!(e.is_some());
if let Some(e) = e {
    assert_eq!(e.sn(), "shortName");
}

Implementations

impl<'a> OidRegistry<'a>

pub fn insert<E>(&mut self, oid: Oid<'a>, entry: E) -> Option<OidEntry>

where E: Into<OidEntry>,

Insert a new entry

pub fn get(&self, oid: &Oid<'a>) -> Option<&OidEntry>

Returns a reference to the registry entry, if found for this OID.

pub fn keys(&self) -> impl Iterator<Item = &Oid<'a>>

Return an Iterator over references to the OID numbers (registry keys)

pub fn values(&self) -> impl Iterator<Item = &OidEntry>

Return an Iterator over references to the OidEntry values

pub fn iter(&self) -> impl Iterator<Item = (&Oid<'a>, &OidEntry)>

Return an Iterator over references to the (Oid, OidEntry) key/value pairs

pub fn iter_by_sn<S: Into<String>>( &self, sn: S, ) -> impl Iterator<Item = (&Oid<'a>, &OidEntry)>

Return the (Oid, OidEntry) key/value pairs, matching a short name

The registry should not contain entries with same short name to avoid ambiguity, but it is not mandatory.

This function returns an iterator over the key/value pairs. In most cases, it will have 0 (not found) or 1 item, but can contain more if there are multiple definitions.

// iterate all entries matching "shortName"
for (oid, entry) in registry.iter_by_sn("shortName") {
    // do something
}

// if you are *sure* that there is at most one entry:
let opt_sn = registry.iter_by_sn("shortName").next();
if let Some((oid, entry)) = opt_sn {
    // do something
}

pub fn with_crypto(self) -> Self

Populate registry with common crypto OIDs (encryption, hash algorithms)

pub fn with_all_crypto(self) -> Self
