reqsign-file-read-tokio

Tokio-based file reading implementation for reqsign.

This crate provides TokioFileRead, an async file reader that implements the FileRead trait from reqsign_core using Tokio's file system operations.

Quick Start

use reqsign_core::Context;
use reqsign_file_read_tokio::TokioFileRead;

// Create a context with Tokio file reader
let ctx = Context::new(
    TokioFileRead::default(),
    http_client, // Your HTTP client
);

// Read files asynchronously
let content = ctx.file_read("/path/to/file").await?;

Features

• Async File I/O: Leverages Tokio's async file system operations
• Zero Configuration: Works out of the box with sensible defaults
• Lightweight: Minimal dependencies, only what's needed

Use Cases

This crate is essential when:

• Loading credentials from file system (e.g., ~/.aws/credentials)
• Reading service account keys (e.g., Google Cloud service account JSON)
• Accessing configuration files for various cloud providers

Examples

Reading Credentials

Check out the read_credentials example to see how to read credential files:

cargo run --example read_credentials -- ~/.aws/credentials

Integration with Services

use reqsign_core::{Context, Signer};
use reqsign_file_read_tokio::TokioFileRead;
use reqsign_http_send_reqwest::ReqwestHttpSend;

// Create context with Tokio file reader
let ctx = Context::new(
    TokioFileRead::default(),
    ReqwestHttpSend::default(),
);

// Use with any service that needs file access
let signer = Signer::new(ctx, loader, builder);

Requirements

• Tokio runtime with fs feature enabled
• Compatible with all reqsign service implementations
