Struct PackageAnnouncement 

#[non_exhaustive]
pub struct PackageAnnouncement {
    pub collection_id: Uuid,
    pub name: String,
    pub version: String,
    pub sequence: u64,
    pub manifest: Hash,
    pub manifest_ticket: String,
    pub publisher: String,
}

A gossip announcement for a publicly fetchable collection manifest.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

collection_id: Uuid

name: String

version: String

sequence: u64

manifest: Hash

manifest_ticket: String

publisher: String

Implementations

impl PackageAnnouncement

pub fn new( collection_id: Uuid, name: impl Into<String>, version: impl Into<String>, sequence: u64, manifest: Hash, manifest_ticket: impl Into<String>, publisher: PublicKey, ) -> Result<Self>

Errors

Returns an error if the ticket is invalid or does not identify the announced manifest.

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

Errors

Returns an error if the announcement has invalid metadata or a ticket that does not match the manifest hash.

pub fn to_bytes(&self) -> Result<Vec<u8>>

Errors

Returns an error if the announcement is invalid or cannot be encoded.

pub fn from_bytes(bytes: impl AsRef<[u8]>) -> Result<Self>

Errors

Returns an error if the announcement cannot be decoded or validated.

pub fn ticket(&self) -> Result<BlobTicket>

Parse the manifest blob ticket carried by this announcement.

Errors

Returns an error if the ticket is invalid.
