Struct LazyMessage 

pub struct LazyMessage {
    pub headers: MessageHeaders,
    pub properties: MessageProperties,
    pub content_type: String,
    pub content_encoding: String,
    /* private fields */
}

Lazy-deserialized message

Headers and properties are eagerly deserialized (they’re small), but the body is lazily deserialized only when accessed.

Fields

headers: MessageHeaders

Message headers (eagerly deserialized)

properties: MessageProperties

Message properties (eagerly deserialized)

content_type: String

Content type

content_encoding: String

Content encoding

Implementations

impl LazyMessage

pub fn from_json(data: &[u8]) -> Result<Self, LazyError>

Create a lazy message from JSON bytes

This performs minimal deserialization - only headers and properties are parsed. The body remains in raw form until accessed.

pub fn task_id(&self) -> Uuid

Get the task ID

pub fn task_name(&self) -> &str

Get the task name

pub fn body_size(&self) -> usize

Get the body size without deserializing

pub fn is_body_cached(&self) -> bool

Check if body is already deserialized

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

Get raw body bytes without deserializing

pub fn body(&self) -> Result<Vec<u8>, LazyError>

Get deserialized body (triggers deserialization if not cached)

pub fn has_eta(&self) -> bool

Check if message has ETA

pub fn has_expires(&self) -> bool

Check if message has expiration

pub fn has_parent(&self) -> bool

Check if message has parent

pub fn has_root(&self) -> bool

Check if message has root

pub fn has_group(&self) -> bool

Check if message has group

pub fn into_message(self) -> Result<Message, LazyError>

Convert to fully deserialized message

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for LazyMessage
