goosefs-sdk 0.1.1

//! Goosefs Rust gRPC Client
//!
//! A Rust client library that communicates with Goosefs Master/Worker
//! via gRPC (tonic/protobuf). This is the **Layer 3** crate in the
//! Lance → OpenDAL → Goosefs architecture.

//! # Quick Start — High-Level API
//!
//! ```rust,no_run
//! use std::sync::Arc;
//! use goosefs_sdk::context::FileSystemContext;
//! use goosefs_sdk::io::{GoosefsFileWriter, GoosefsFileReader};
//! use goosefs_sdk::config::GoosefsConfig;
//!
//! #[tokio::main]
//! async fn main() -> goosefs_sdk::error::Result<()> {
//!     // Build once — the only call that performs TCP+SASL.
//!     let ctx = FileSystemContext::connect(GoosefsConfig::new("127.0.0.1:9200")).await?;
//!
//!     // Write a file (zero new connections — reuses ctx).
//!     GoosefsFileWriter::write_file_with_context(ctx.clone(), "/my-file.txt", b"Hello!").await?;
//!
//!     // Read it back.
//!     let data = GoosefsFileReader::read_file_with_context(ctx.clone(), "/my-file.txt").await?;
//!     println!("read {} bytes", data.len());
//!
//!     Ok(())
//! }
//! ```
//!
//! # Low-Level API
//!
//! ```rust,no_run
//! use goosefs_sdk::client::MasterClient;
//! use goosefs_sdk::config::GoosefsConfig;
//!
//! #[tokio::main]
//! async fn main() -> goosefs_sdk::error::Result<()> {
//!     let config = GoosefsConfig::default();
//!     let master = MasterClient::connect(&config).await?;
//!     let file_info = master.get_status("/my-file.txt").await?;
//!     println!("file length: {:?}", file_info.length);
//!     Ok(())
//! }
//! ```
