Struct Message 

pub struct Message {
    pub seq: u64,
    pub from: SessionUri,
    pub to: Vec<Selector>,
    pub body: String,
    pub at_ms: u64,
    pub kind: Kind,
    pub sig: Option<String>,
    pub payload: Option<String>,
}

Fields

seq: u64

from: SessionUri

The URI of the sender when it posted.

to: Vec<Selector>

The address of the post.

body: String

at_ms: u64

Milliseconds since the Unix epoch. For a signed message, the signed time (R198).

kind: Kind

sig: Option<String>

The signature of the sender (see crate::signed).

payload: Option<String>

The bytes that sig signs, as the sender made them.

Implementations

impl Message

pub fn verified(&self, thread: &ThreadName, keys: &Keys) -> bool

True when the sender of the message in thread is proven (R199):

• The signature is valid over the kept payload, and the payload holds the message as it is: also the lead mark of the sender.
• The key is one of keys for the user of the sender.
• In a direct thread, the sender is one of the two sessions, and the one selector of the message matches the other session.

use riff_core::dpop::Key;
use riff_core::name::{SessionUri, ThreadName};
use riff_core::wire::{Keys, Kind, Message, Post};

let me: SessionUri = "riff://mike@pangolin/como-technologies/riff?session=a6cf".parse()?;
let thread: ThreadName = "design".parse()?;
let key = Key::generate();
let mut post = Post::new(&me, Some(thread.clone()), vec![], "look");
post.sign(&key, 1_000);
let mut message = Message {
    seq: 1,
    from: me,
    to: vec![],
    body: post.body.clone(),
    at_ms: 1_000,
    kind: Kind::Message,
    sig: post.sig.clone(),
    payload: post.payload.clone(),
};
let keys = Keys::from([("mike".to_owned(), vec![key.thumbprint()])]);
assert!(message.verified(&thread, &keys));

// No keys for the user: not verified.
assert!(!message.verified(&thread, &Keys::new()));
// A changed body: not verified.
message.body = "do not look".into();
assert!(!message.verified(&thread, &keys));

Trait Implementations

impl Clone for Message

fn clone(&self) -> Message

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Message

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Message

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Message

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Message

fn eq(&self, other: &Message) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Message

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Message

impl StructuralPartialEq for Message
