Struct MsgMeta 

pub struct MsgMeta {
    pub schema_id: u64,
    pub msg_type: u32,
    pub msg_version: u16,
    pub flags: u16,
}

Expected message identity for receive-side filtering.

This identity is stored in the v1 envelope header and validated by typed receive helpers.

Fields

schema_id: u64

Schema identifier for the message family.

msg_type: u32

Message type identifier within the schema.

msg_version: u16

Message version.

flags: u16

Header flags.

Most callers leave this as 0 and use MsgMeta::with_flags when needed.

Implementations

impl MsgMeta

pub const fn new(schema_id: u64, msg_type: u32, msg_version: u16) -> Self

Construct a message identity with default flags = 0.

pub const fn with_flags(self, flags: u16) -> Self

Return a copy of this identity with flags updated.

Trait Implementations

impl Clone for MsgMeta

fn clone(&self) -> MsgMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MsgMeta

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

Formats the value using the given formatter.

impl PartialEq for MsgMeta

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