Immutable description of a collection version.

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.

schema_version: u32

collection_id: Uuid

version: String

parent: Option<Hash>

changelog: Option<String>

entries: Vec<CollectionEntry>

package: Option<PackageProfile>

signature: Option<String>

public_key: Option<String>

content_type: Option<ContentType>

Content type taxonomy — None means the collection behaves as a generic file set (default, backward-compatible behaviour).

editorial_state: Option<EditorialState>

Editorial lifecycle stage — None means the collection is in the implicit Published state (backward-compatible).

channels: Vec<Channel>

Channels this collection version should be announced on.

An empty list means the collection is broadcast only on the default public catalog topic.

metadata: Option<PackageMetadata>

Application-specific metadata (optional).

Implementations

impl CollectionManifest

pub fn new(collection_id: Uuid, version: impl Into<String>) -> Self

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

Errors

Returns an error when the schema, version, paths, dependencies, or duplicate entries are invalid.

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

Errors

Returns an error when the manifest is invalid or cannot be serialized.

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

Errors

Returns an error when the manifest cannot be decoded or is invalid.

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

Serialize the manifest without its signature.

The public key remains part of this representation so changing the signer changes the manifest identity.

Errors

Returns an error when the manifest is invalid or cannot be serialized.

pub fn sign(&mut self, signing_key: &SigningKey) -> Result<()>

Sign the manifest with an Ed25519 maintainer key.

The signature is encoded as lowercase hexadecimal in the manifest.

Errors

Returns an error when the manifest is invalid or cannot be serialized.

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

Verify the manifest’s embedded Ed25519 signature.

Unsigned manifests have no signature to verify and return Ok(()); a partially signed manifest is rejected.

Errors

Returns an error when signature metadata is malformed or verification fails.

pub fn version_ordering(&self, other_manifest: &Self) -> Result<Ordering>

Compare this manifest’s semver version with another manifest.

Errors

Returns an error when either manifest contains an invalid semver version.

pub fn is_upgrade_from(&self, other: &Self) -> Result<bool>

Return whether this manifest is a newer version than another manifest.

Errors

Returns an error when either manifest contains an invalid semver version.

pub fn dependencies_satisfied( &self, available: &BTreeMap<Uuid, Version>, ) -> Result<bool>

Check whether all package dependencies are available.

Errors

Returns an error when package metadata or dependency requirements are invalid.

pub fn content_id(&self) -> Result<Hash>

Errors

Returns an error when the manifest cannot be serialized.

pub fn blob_id(&self) -> Result<Hash>

Return the content hash of the serialized manifest blob.

This differs from Self::content_id for signed manifests because the signature is intentionally excluded from the logical manifest ID.

Errors

Returns an error when the manifest is invalid or cannot be serialized.

pub const fn has_editorial_metadata(&self) -> bool

Whether this collection has opted into editorial flows.

pub fn effective_state(&self) -> EditorialState

The effective editorial state (defaults to Published).

pub fn effective_content_type(&self) -> &ContentType

The effective content type (defaults to Generic).
