Struct GroupId 

pub struct GroupId { /* private fields */ }

A group ID. The group ID is chosen by the creator of the group and should be globally unique.

Implementations

impl GroupId

pub fn random(rng: &impl OpenMlsRand) -> GroupId

Create a new (random) group ID.

Group IDs should be random and not be misused as, e.g., a group name.

pub fn from_slice(bytes: &[u8]) -> GroupId

Create a group ID from a byte slice.

This should be used only if the group ID is chosen by an entity that ensures uniqueness.

pub fn as_slice(&self) -> &[u8]

Returns the group ID as a byte slice.

pub fn to_vec(&self) -> Vec<u8>

Returns the group ID as a byte vector.

Trait Implementations

impl Clone for GroupId

fn clone(&self) -> GroupId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GroupId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GroupId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Deserialize for GroupId

fn tls_deserialize<R>(bytes: &mut R) -> Result<GroupId, Error>

where R: Read,

This function deserializes the bytes from the provided a std::io::Read and returns the populated struct.

fn tls_deserialize_exact(bytes: impl AsRef<[u8]>) -> Result<Self, Error>

where Self: Sized,

This function deserializes the provided bytes and returns the populated struct. All bytes must be consumed.

impl DeserializeBytes for GroupId

fn tls_deserialize_bytes(bytes: &[u8]) -> Result<(GroupId, &[u8]), Error>

This function deserializes the bytes from the provided a &[u8] and returns the populated struct, as well as the remaining slice.

fn tls_deserialize_exact_bytes(bytes: &[u8]) -> Result<Self, Error>

where Self: Sized,

This function deserializes the provided bytes and returns the populated struct. All bytes must be consumed.

impl Hash for GroupId

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 GroupId

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

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

fn partial_cmp(&self, other: &GroupId) -> 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 &GroupId

fn tls_serialize<W>(&self, writer: &mut W) -> Result<usize, Error>

where W: Write,

Serialize self and write it to the writer. The function returns the number of bytes written to writer.

fn tls_serialize_detached(&self) -> Result<Vec<u8>, Error>

Serialize self and return it as a byte vector.

impl Serialize for GroupId
