Struct MessageId 

pub struct MessageId(pub Hash);

A unique identifier for messages

This is a Blake3 hash that uniquely identifies message content, computed from the message’s serialized bytes (excluding signature to handle ML-DSA randomness).

Tuple Fields

0: Hash

Implementations

impl MessageId

pub fn new(hash: Hash) -> Self

Create a new MessageId from a Hash

pub fn from_content(content: &[u8]) -> Self

Create a MessageId by hashing the given content

pub fn from_bytes(bytes: [u8; 32]) -> Self

Create a MessageId from raw bytes

pub fn as_bytes(&self) -> &[u8; 32]

Get the underlying bytes

pub fn to_hex(&self) -> String

Convert to hex string for display

Methods from Deref<Target = Hash>

pub fn as_bytes(&self) -> &[u8; 32]

The raw bytes of the Hash. Note that byte arrays don’t provide constant-time equality checking, so if you need to compare hashes, prefer the Hash type.

pub fn to_hex(&self) -> ArrayString<blake3::::{impl#0}::to_hex::{constant#0}>

Encode a Hash in lowercase hexadecimal.

The returned ArrayString is a fixed size and doesn’t allocate memory on the heap. Note that ArrayString doesn’t provide constant-time equality checking, so if you need to compare hashes, prefer the Hash type.

Trait Implementations

impl AsRef<[u8]> for MessageId

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for MessageId

fn clone(&self) -> MessageId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageId

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

Formats the value using the given formatter.

impl Deref for MessageId

type Target = Hash

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for MessageId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for MessageId

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

Formats the value using the given formatter.

impl From<[u8; 32]> for MessageId

fn from(bytes: [u8; 32]) -> Self

Converts to this type from the input type.

impl From<Hash> for MessageId

fn from(hash: Hash) -> Self

Converts to this type from the input type.

impl FromSql for MessageId

fn column_result(value: ValueRef<'_>) -> FromSqlResult<Self>

Converts SQLite value into Rust value.

impl Hash for MessageId

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 Ord for MessageId

fn cmp(&self, other: &Self) -> 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,

Restrict a value to a certain interval.

impl PartialEq for MessageId

fn eq(&self, other: &MessageId) -> 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 PartialOrd for MessageId

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

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

impl Serialize for MessageId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToSql for MessageId

fn to_sql(&self) -> Result<ToSqlOutput<'_>>

Converts Rust value to SQLite value

impl Copy for MessageId

impl Eq for MessageId
