Struct CratesDocsServer 

pub struct CratesDocsServer { /* private fields */ }

Crates Docs MCP Server

Main server struct, managing configuration, tool registry, and cache. Supports multiple transport protocols: stdio, HTTP, SSE, Hybrid.

Fields

• config: Application configuration
• tool_registry: Tool registry
• cache: Cache instance

Implementations

impl CratesDocsServer

pub fn new(config: AppConfig) -> Result<Self>

Create new server instance (synchronous)

Arguments

• config - Application configuration

Errors

Returns error if cache creation fails

Note

This method only supports memory cache. For Redis, use new_async.

Example

use crates_docs::{AppConfig, CratesDocsServer};

let config = AppConfig::default();
let server = CratesDocsServer::new(config).expect("Failed to create server");

pub async fn new_async(config: AppConfig) -> Result<Self>

Create new server instance (async)

Arguments

• config - Application configuration

Errors

Returns error if cache creation fails

Note

Supports memory cache and Redis cache (requires cache-redis feature).

Example

use crates_docs::{AppConfig, CratesDocsServer};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config = AppConfig::default();
    let server = CratesDocsServer::new_async(config).await?;
    Ok(())
}

pub fn config(&self) -> &AppConfig

pub fn tool_registry(&self) -> &Arc<ToolRegistry>

Get tool registry

pub fn cache(&self) -> &Arc<dyn Cache>

Get cache instance

pub fn server_info(&self) -> InitializeResult

Get server info

Returns MCP initialization result with server metadata and capabilities

pub async fn run_stdio(&self) -> Result<()>

Errors

Returns error if server startup fails

pub async fn run_http(&self) -> Result<()>

Run HTTP server

Errors

Returns error if server startup fails

pub async fn run_sse(&self) -> Result<()>
