Struct MailFolderResolutionGeneration

Namespace

MailFathom.Domain.Folders

Assembly

MailFathom.Domain.dll

Counts how many times an alias has been bound to a remote folder.

public readonly record struct MailFolderResolutionGeneration : IEquatable<MailFolderResolutionGeneration>

Implements

IEquatable<MailFolderResolutionGeneration>

Inherited Members

ValueType.Equals(object)

ValueType.GetHashCode()

object.Equals(object, object)

object.GetType()

object.ReferenceEquals(object, object)

Remarks

The generation is what keeps a repointed alias safe. UIDVALIDITY is unique inside one mailbox and says nothing across mailboxes, so two unrelated remote folders can advertise the same value. An alias that moved between them while keeping one persistence identity would let the previous folder's checkpoint apply to the new one and skip every message below its last-seen UID, silently and permanently. Each binding therefore synchronizes under its own generation, with its own checkpoint and its own stored occurrences.

Properties

Creates a generation from a persisted value.

Next()

Starts the generation that a new remote binding of the same alias synchronizes under.
