Struct ComponentMetadata 

pub struct ComponentMetadata {
    pub component_type: i32,
    pub permissions: Option<ComponentPermissions>,
    pub external_committer_permissions: Option<ComponentPermissions>,
}

Metadata describing a component: its data type and permission policies.

Stored as the value in the component registry (ComponentId 0x8000). Each registered component has one of these describing what kind of data it holds and who can insert, update, or delete it.

Fields

component_type: i32

The data structure type of the component’s value

permissions: Option<ComponentPermissions>

Permission policies for this component, evaluated against regular (member-issued) commits.

external_committer_permissions: Option<ComponentPermissions>

Permission policies for this component, evaluated against MLS External Commits (RFC 9420 §12.4.3.2). Absent / unset is equivalent to all-Deny: external committers cannot touch this component. Each component opts in explicitly by setting this field. Combined with the EXTERNAL_COMMIT_POLICY master switch (allow_external_commit), this is the per-component declarative authorization for external-commit-driven joins.

Implementations

impl ComponentMetadata

pub fn component_type(&self) -> ComponentType

Returns the enum value of component_type, or the default if the field is set to an invalid enum value.

pub fn set_component_type(&mut self, value: ComponentType)

Sets component_type to the provided enum value.

Trait Implementations

impl Clone for ComponentMetadata

fn clone(&self) -> ComponentMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentMetadata

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

Formats the value using the given formatter.

impl Default for ComponentMetadata

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ComponentMetadata

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for ComponentMetadata

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl Name for ComponentMetadata

const NAME: &'static str = "ComponentMetadata"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

const PACKAGE: &'static str = "xmtp.mls.message_contents"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing into the google.protobuf.Any type.

impl PartialEq for ComponentMetadata

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

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
