StreamDescriptor class

A descriptor for a transfer that happens outside Trust Task documents, at an address the recipient publishes — the stream algorithm, and any other algorithm a recipient offers that is shaped as an address plus a bearer credential. Identical in members to the vta/backup/*/1.0 descriptor.

Constructors

StreamDescriptor({required BundleId bundleId, required String algorithm, required String transportUrl, required String transportToken, required ExpectedSha256 expectedSha256, required ExpectedSizeBytes expectedSizeBytes, required ExpiresAt expiresAt})

const

StreamDescriptor.fromJson(Map<String, dynamic> json)

Read this payload from a decoded JSON object.

Properties

algorithm → String

The mechanism in use. Never chunkedTrustTask, which has its own descriptor shape; a descriptor naming it with a transport address is malformed.

final

bundleId → String

final

expectedSha256 → String

final

expectedSizeBytes → ChunkCount

final

expiresAt → String

final

hashCode → ChunkCount

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

transportToken → String

Bearer credential for transportUrl, presented in the X-Backup-Token header. Minted per bundle and never reused. A recipient should store only a hash of it, and should accept an export token once.

final

transportUrl → String

Where to fetch (export) or write (import) the bytes. A recipient with no address at which it is reachable cannot produce this and refuses with transportUnavailable rather than returning an unusable one. An import address is write-only: staged bytes are never served back from it.

final

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson() → Map<String, dynamic>

Serialize to a JSON-encodable map, omitting absent members.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
