Struct Label 

pub struct Label {
    pub name: String,
    pub sort: PayloadSort,
}

A message label with its payload sort.

Labels identify message types in communications. Each label has a name and an associated payload type.

Examples

use telltale_types::{Label, PayloadSort};

// Simple label with unit payload
let hello = Label::new("hello");
assert_eq!(hello.name, "hello");

// Label with typed payload
let data = Label::with_sort("data", PayloadSort::Nat);
assert!(!data.sort.is_simple() || matches!(data.sort, PayloadSort::Nat));

Fields

name: String

The label name identifying this message type

sort: PayloadSort

The payload sort for this message

Implementations

impl Label

pub fn new(name: impl Into<String>) -> Self

Create a new label with unit payload

pub fn with_sort(name: impl Into<String>, sort: PayloadSort) -> Self

Create a new label with a specific sort

pub fn matches(&self, other: &Label) -> bool

Check if this label matches another exactly (name and sort).

pub fn matches_name(&self, name: &str) -> bool

Check if this label matches a name

Trait Implementations

impl Clone for Label

fn clone(&self) -> Label

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Contentable for Label

fn to_bytes(&self) -> Result<Vec<u8>, ContentableError>

Serialize to canonical byte representation (JSON format).

fn from_bytes(bytes: &[u8]) -> Result<Self, ContentableError>

Deserialize from JSON bytes.

fn to_template_bytes(&self) -> Result<Vec<u8>, ContentableError>

Serialize to template bytes, allowing open terms with explicit free-variable interfaces when supported by the implementation.

fn content_id<H: Hasher>(&self) -> Result<ContentId<H>, ContentableError>

Compute content ID using the specified hasher (from JSON bytes).

fn content_id_default( &self, ) -> Result<ContentId<DefaultContentHasher>, ContentableError>

Compute content ID using the central default content hasher (from JSON bytes).

fn content_id_blake3(&self) -> Result<ContentId<Blake3Hasher>, ContentableError>

Compute content ID using explicit BLAKE3 (from JSON bytes).

fn template_id<H: Hasher>(&self) -> Result<ContentId<H>, ContentableError>

Compute a template ID using the specified hasher (from template bytes).

fn template_id_default( &self, ) -> Result<ContentId<DefaultContentHasher>, ContentableError>

Compute a template ID using the central default content hasher.

fn template_id_blake3( &self, ) -> Result<ContentId<Blake3Hasher>, ContentableError>

Compute a template ID using explicit BLAKE3.

impl Debug for Label

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Label

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Label

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

Formats the value using the given formatter.

impl Hash for Label

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

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 PartialEq for Label

fn eq(&self, other: &Label) -> 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 Label

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 Label
