Struct ParticipantId 

pub struct ParticipantId(/* private fields */);

One participant in a shared record: a person’s window or an agent task. Each participant owns its own view state (caret, selection, Find), and the app builds that participant’s resource tree from it (the toolkit’s PublishesResources::resources_for).

Opaque, non-empty, ASCII-printable and at most MAX_PARTICIPANT_ID_BYTES bytes. It is a routing key for view state, never authority: the authenticated principal is ActionInvoker::actor.

Implementations

impl ParticipantId

pub fn new(id: impl Into<String>) -> Result<ParticipantId, String>

Validate and wrap a participant id.

Errors

Returns a description when id is empty, longer than MAX_PARTICIPANT_ID_BYTES, or not printable ASCII.

pub fn as_str(&self) -> &str

pub fn for_agent_task(task_id: &str) -> Result<ParticipantId, String>

The participant of one agent task. Only the host derives it, from the task it admitted (never from anything the agent sends), so an agent can address only the view of the task it runs.

Errors

Returns a description when the derived id is not a valid participant id (see ParticipantId::new).

pub fn for_execution(execution: Uuid) -> ParticipantId

One host-minted execution’s private view. This key is subordinate to the admitted principal and confers no authority. Hosts derive it from their execution lease, never a client-supplied run label or context.

pub fn agent_task(&self) -> Option<&str>

The task id of a host-derived agent task participant.

Trait Implementations

impl Clone for ParticipantId

fn clone(&self) -> ParticipantId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParticipantId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ParticipantId

fn deserialize<__D>( __deserializer: __D, ) -> Result<ParticipantId, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ParticipantId

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

Formats the value using the given formatter.

impl From<ParticipantId> for String

fn from(value: ParticipantId) -> String

Converts to this type from the input type.

impl Hash for ParticipantId

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ParticipantId

fn cmp(&self, other: &ParticipantId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl PartialEq for ParticipantId

fn eq(&self, other: &ParticipantId) -> 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.

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

Tests greater than (for self and other) and is used by the > operator.

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

impl Serialize for ParticipantId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<String> for ParticipantId

type Error = String

The type returned in the event of a conversion error.

fn try_from( value: String, ) -> Result<ParticipantId, <ParticipantId as TryFrom<String>>::Error>

Performs the conversion.
