Struct GCloudLayerConfig 

pub struct GCloudLayerConfig<M: LogMapper = DefaultLogMapper> { /* private fields */ }

Configuration for setting up Google Cloud logging with tracing.

GCloudLayerConfig holds everything needed to build a tracing_stackdriver layer that sends logs to Google Cloud Logging. It supports custom log mappers, batching, and uses service account credentials for authentication.

Use .build_layer() to produce a ready-to-use tracing layer.

Implementations

impl<M: LogMapper> GCloudLayerConfig<M>

pub fn build_layer( self, ) -> Result<(Layer<Registry, impl Fn() -> GoogleWriterHandle>, GoogleWriterRuntime<M>), LoggerError>

Builds a tracing_stackdriver layer using this config.

Creates a GoogleLogger from the provided log name and credentials, then wraps it in a GoogleWriter for async batching. Returns a tracing_stackdriver layer that can be added to a subscriber.

Example

use tracing_gcloud_layer::DefaultGCloudLayerConfigBuilder;
use tracing_subscriber::prelude::*;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let svc_account_bytes = std::fs::read("svc-account.json")?;

    let (layer, runtime) = DefaultGCloudLayerConfigBuilder::default()
        .log_name("my-service")
        .logger_credential(svc_account_bytes)
        .build()?
        .build_layer()?;

    tracing_subscriber::registry().with(layer).init();
    runtime.shutdown().await;
    Ok(())
}

Trait Implementations

impl<M: Clone + LogMapper> Clone for GCloudLayerConfig<M>

fn clone(&self) -> GCloudLayerConfig<M>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
