Struct DMSCObservabilityModule 

pub struct DMSCObservabilityModule { /* private fields */ }

Main observability module for DMSC.

This module provides distributed tracing and metrics collection capabilities, following modern observability best practices. It implements the ServiceModule trait for seamless integration with the DMSC application lifecycle.

Implementations

impl DMSCObservabilityModule

pub fn new() -> Self

Creates a new observability module with default configuration.

Returns

A new DMSCObservabilityModule instance with default configuration

pub fn with_config(self, config: DMSCObservabilityConfig) -> Self

Configures the observability module with custom settings.

Parameters

• config: The custom configuration to apply

Returns

The updated DMSCObservabilityModule instance

pub fn export_data(&self) -> DMSCObservabilityData

Exports observability data.

This method collects and returns the current observability data, including metrics in Prometheus format and information about active traces and spans.

Returns

A DMSCObservabilityData struct containing the exported observability data

Trait Implementations

impl DMSCModule for DMSCObservabilityModule

fn name(&self) -> &str

Returns the name of the observability module.

Returns

The module name as a string

fn is_critical(&self) -> bool

Indicates whether the observability module is critical.

The observability module is non-critical, meaning that if it fails to initialize or operate, it should not break the entire application. This allows the core functionality to continue even if observability features are unavailable.

Returns

false since observability is non-critical

fn init<'life0, 'life1, 'async_trait>( &'life0 mut self, ctx: &'life1 mut DMSCServiceContext, ) -> Pin<Box<dyn Future<Output = DMSCResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Initializes the observability module.

This method performs the following steps:

1. Loads configuration from the service context
2. Initializes tracing with the configured sampling rate
3. Initializes the metrics registry
4. Creates common service metrics
5. Registers lifecycle hooks for automatic metrics collection
6. Logs initialization completion

Parameters

• ctx: The service context containing configuration and other services

Returns

A DMSCResult<()> indicating success or failure

fn after_shutdown<'life0, 'life1, 'async_trait>( &'life0 mut self, ctx: &'life1 mut DMSCServiceContext, ) -> Pin<Box<dyn Future<Output = DMSCResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Performs cleanup after the application has shut down.

This method exports the final observability data and logs information about active traces and spans at the time of shutdown.

Parameters

• ctx: The service context containing the logger service

Returns

A DMSCResult<()> indicating success or failure

fn priority(&self) -> i32

Returns the priority of the module.

fn dependencies(&self) -> Vec<&str>

Returns the list of module dependencies.

fn before_start<'life0, 'life1, 'async_trait>( &'life0 mut self, _ctx: &'life1 mut DMSCServiceContext, ) -> Pin<Box<dyn Future<Output = DMSCResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Prepares the module for startup.

fn start<'life0, 'life1, 'async_trait>( &'life0 mut self, _ctx: &'life1 mut DMSCServiceContext, ) -> Pin<Box<dyn Future<Output = DMSCResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Starts the service module.

fn after_start<'life0, 'life1, 'async_trait>( &'life0 mut self, _ctx: &'life1 mut DMSCServiceContext, ) -> Pin<Box<dyn Future<Output = DMSCResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Performs post-startup operations.

fn before_shutdown<'life0, 'life1, 'async_trait>( &'life0 mut self, _ctx: &'life1 mut DMSCServiceContext, ) -> Pin<Box<dyn Future<Output = DMSCResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Prepares the module for shutdown.

fn shutdown<'life0, 'life1, 'async_trait>( &'life0 mut self, _ctx: &'life1 mut DMSCServiceContext, ) -> Pin<Box<dyn Future<Output = DMSCResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Shuts down the service module.

impl Default for DMSCObservabilityModule

fn default() -> Self

type Output = Bound<'py, <DMSCObservabilityModule as IntoPyObject<'py>>::Target>

The smart pointer type to use.

type Error = PyErr

The type returned in the event of a conversion error.

fn into_pyobject( self, py: Python<'py>, ) -> Result<<Self as IntoPyObject<'_>>::Output, <Self as IntoPyObject<'_>>::Error>

Performs the conversion.

impl PyClass for DMSCObservabilityModule

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for DMSCObservabilityModule

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

#[pyclass(sequence)]

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<DMSCObservabilityModule>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable
