Meshline.Models.Protocol
ChannelPost Class
Contains the device-signed content of a public channel post.
public sealed record ChannelPost : Meshline.Models.Protocol.TypedProtocolModel, System.IEquatable<Meshline.Models.Protocol.ChannelPost>
Inheritance System.Object → ProtocolModel → TypedProtocolModel → ChannelPost
Implements System.IEquatable<ChannelPost>
Constructors
ChannelPost() Constructor
Contains the device-signed content of a public channel post.
public ChannelPost();
Properties
ChannelPost.Attachments Property
The content references attached to the message.
public System.Nullable<System.Collections.Immutable.ImmutableArray<Meshline.Models.Protocol.ContentReference>> Attachments { get; init; }
Property Value
System.Nullable<System.Collections.Immutable.ImmutableArray<ContentReference>>
ChannelPost.Body Property
The optional plaintext message body.
public Meshline.Models.Protocol.MessageBody? Body { get; init; }
Property Value
ChannelPost.ChannelId Property
The channel's canonical chan_ identifier.
public string ChannelId { get; init; }
Property Value
ChannelPost.DeviceSignature Property
The device signature over the model's device signing input.
public System.Collections.Immutable.ImmutableArray<byte> DeviceSignature { get; init; }
Property Value
System.Collections.Immutable.ImmutableArray<System.Byte>
ChannelPost.MessageId Property
The message's canonical msg_ identifier.
public string MessageId { get; init; }
Property Value
Methods
ChannelPost.GetSigningInput(NetworkContext) Method
Builds the canonical, network-bound bytes used to sign or verify this document.
public byte[] GetSigningInput(Meshline.Models.NetworkContext context);
Parameters
context NetworkContext
The network context bound into identifiers or signing input.
Returns
System.Byte[]
The canonical UTF-8 signing input bound to the network context, with the applicable signature fields omitted.
Exceptions
System.Text.Json.JsonException
The signing payload cannot be represented as canonical protocol JSON, contains conflicting extension fields, or already contains a root $context property.
ChannelPost.Validate(NetworkContext) Method
Validates the post identifiers, body, attachments, and signature length.
public override Meshline.Validation.ProtocolViolation? Validate(Meshline.Models.NetworkContext? context=null);
Parameters
context NetworkContext
The optional network context passed to nested validation when needed; field-only validation may ignore it.
Returns
ProtocolViolation
The first detected protocol violation, or null if the implemented checks pass.
Remarks
These checks do not verify the external device signature or establish current signer authorization. Verify the signature and the applicable device-state or resource authorization evidence separately.
