Crate 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.

Overview

TokioFileRead enables reqsign to read files asynchronously using Tokio’s efficient async I/O primitives. This is particularly useful when loading credentials or configuration from the file system.

Example

use reqsign_core::{Context, OsEnv};
use reqsign_file_read_tokio::TokioFileRead;

#[tokio::main]
async fn main() {
    // Create a context with Tokio file reader
    let ctx = Context::new()
        .with_file_read(TokioFileRead::default())
        .with_env(OsEnv);

    // The context can now read files asynchronously
    match ctx.file_read("/path/to/credentials.json").await {
        Ok(content) => println!("Read {} bytes", content.len()),
        Err(e) => eprintln!("Failed to read file: {}", e),
    }
}

Usage with Service Signers

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

// Many cloud services require reading credentials from files
let ctx = Context::new()
    .with_file_read(TokioFileRead::default());

// Create a signer that can load credentials from files
// let signer = Signer::new(ctx, credential_loader, request_builder);
