Crate nostr_types

This crate provides types for nostr protocol handling.

Structs

• DelegationConditions
  Conditions of delegation

  This is an encrypted private key.
• EventAddr
  An ‘naddr’: data to address a possibly parameterized replaceable event (d-tag, kind, author, and relays)
• EventKindIterator
  Iterator over well known EventKinds
• EventPointer
  An ‘nevent’: event id along with some relays in which that event may be found.
• EventV1
  The main event type

  An event identifier, constructed as a SHA256 hash of the event fields according to NIP-01, as a hex string
• KeySigner
  Signer with a local private key (and public key)
• MetadataV1
  Metadata about a user
• MilliSatoshi
  Bitcoin amount measured in millisatoshi
• Nip05V1
  The content of a webserver’s /.well-known/nostr.json file used in NIP-05 and NIP-35 This allows lookup and verification of a nostr user via a user@domain style identifier.
• NostrUrl
  A Nostr URL (starting with ‘nostr:’)
• PayRequestData
  This is a response from a zapper lnurl
• PreEventV1
  Data used to construct an event
• PreEventV2
  Data used to construct an event
• PreEventV3
  Data used to construct an event
• PrivateKey
  This is a private key which is to be kept secret and is used to prove identity
• Profile
  A person’s profile on nostr which consists of the data needed in order to follow someone.
• PublicKey
  This is a public key, which identifies an actor (usually a person) and is shared.
• PublicKeyHex
  This is a public key, which identifies an actor (usually a person) and is shared, as a hex string
• RelayFeesV1
  Relay fees
• RelayInformationDocumentV1
  Relay information document as described in NIP-11, supplied by a relay
• RelayInformationDocumentV2
  Relay information document as described in NIP-11, supplied by a relay
• RelayLimitationV1
  Relay limitations
• RelayLimitationV2
  Relay limitations
• RelayList
  A relay list, indicating usage for each relay, which can be used to represent the data found in a kind 10002 RelayListMetadata event.
• RelayRetentionV1
  Relay retention
• RelayUrl
  A Url validated as a nostr relay url in canonical form We don’t serialize/deserialize these directly, see UncheckedUrl for that
• RumorV1
  A Rumor is an Event without a signature
• RumorV2
  A Rumor is an Event without a signature
• RumorV3
  A Rumor is an Event without a signature
• ShatteredContent
  A sequence of content segments
• Signature
  A Schnorr signature that signs an Event, taken on the Event Id field
• SignatureHex
  A Schnorr signature that signs an Event, taken on the Event Id field, as a hex string
• SimpleRelayList
  A list of relays with SimpleRelayUsage
• SimpleRelayUsage
  When and how to use a Relay
• Span
  This is like Range<usize>, except we impl offset() on it This is like linkify::Span, except we impl offset() on it and don’t need the as_str() or kind() functions.
• SubscriptionId
  A random client-chosen string used to refer to a subscription
• TagV3
  A tag on an Event
• UncheckedUrl
  A string that is supposed to represent a URL but which might be invalid
• Unixtime
  An integer count of the number of seconds from 1st January 1970. This does not count any of the leap seconds that have occurred, it simply presumes UTC never had leap seconds; yet it is well known and well understood.
• Url
  A String representing a valid URL with an authority present including an Internet based host.
• XOnlyPublicKey
  An x-only public key, used for verification of Taproot signatures and serialized according to BIP-340.
• ZapData
  Data about a Zap

Enums

• ClientMessageV1
  A message from a client to a relay
• ClientMessageV2
  A message from a client to a relay
• ClientMessageV3
  A message from a client to a relay
• ContentEncryptionAlgorithm
  Content Encryption Algorithm
• ContentSegment
  A segment of content
• Error
  Errors that can occur in the nostr-proto crate
• EventDelegation
  Delegation information for an Event
• EventKind
  A kind of Event
• EventKindOrRange
  Either an EventKind or a range (a vector of length 2 with start and end)
• EventReference
  A reference to another event, either by Id (often coming from an ‘e’ tag), or by EventAddr (often coming from an ‘a’ tag).
• Identity
  All states that your identity can be in
• KeySecurity
  This indicates the security of the key by keeping track of whether the secret key material was handled carefully. If the secret is exposed in any way, or leaked and the memory not zeroed, the key security drops to Weak.
• NostrBech32
  A bech32 sequence representing a nostr object (or set of objects)
• RelayMessageV1
  A message from a relay to a client

  A message from a relay to a client

  A message from a relay to a client
• RelayUsage
  Relay Usage
• TagV1
  A tag on an Event
• TagV2
  A tag on an Event
• Why
  The reason why a relay issued an OK or CLOSED message
