fetched info from openWeatherMap Api in Rust

Weather_Api_impl

A Rust implementation that consumes a weather API and exposes a simple, programmatic way to fetch current conditions (and optionally forecasts) for a given location.

Features

• Written in Rust (100%)
• Fetch current weather by city name or lat/long
• Configurable via environment variables
• Clean error handling and typed responses
• Ready to run locally

Note: This README is a template since I don’t have the repository’s source/layout here. If you share the main entry file (e.g., src/main.rs) or the API/provider used, I can tailor this README exactly to your code, commands, and endpoints.

Requirements

• Rust toolchain (stable): https://www.rust-lang.org/tools/install
• An API key for your weather provider (e.g., OpenWeatherMap, WeatherAPI, etc.)

Quick Start

1) Clone

git clone https://github.com/souravk29/Weather_Api_impl.git
cd Weather_Api_impl

2) Configure environment variables

Create a .env file in the project root (or export env vars in your shell):

WEATHER_API_KEY=your_api_key_here
# Optional (depends on your implementation/provider):
WEATHER_BASE_URL=https://api.openweathermap.org
WEATHER_UNITS=metric

If you use dotenvy/dotenv, the app will load .env automatically (if implemented).

3) Build & run

cargo build
cargo run

Usage

How you call the app depends on whether this is a CLI or a web server.

If this is a CLI

Examples (adjust flags to match your implementation):

cargo run -- --city "Kolkata"
cargo run -- --lat 22.5726 --lon 88.3639

If this is a web API (server)

Start the server:

cargo run

Then call an endpoint (example):

curl "http://localhost:8080/weather?city=Kolkata"

Configuration

Common configuration keys used in Rust weather clients:

• WEATHER_API_KEY (required): API key for the provider
• WEATHER_BASE_URL (optional): override provider base URL
• WEATHER_UNITS (optional): metric, imperial, or provider-specific
• RUST_LOG (optional): logging level, e.g. info, debug

Example:

export WEATHER_API_KEY="..."
export RUST_LOG=debug
cargo run

Project Structure (typical)

This is a suggested structure (may differ in your repo):

src/
  main.rs            # entry point
  lib.rs             # library interface (optional)
  client.rs          # HTTP client logic
  models.rs          # response structs
  config.rs          # env/config parsing

Development

Run formatting and linting:

cargo fmt
cargo clippy -- -D warnings

Run tests:

cargo test

Troubleshooting

• 401/403 from provider: check WEATHER_API_KEY
• Network/TLS issues: ensure your system cert store is up-to-date
• Unexpected JSON parsing errors: provider response schema may differ; verify model structs match the API response

License

Add a license if you intend the repo to be reused:

• MIT or Apache-2.0 are common for Rust projects.

Share details to make this README exact

If you paste:

• the weather provider name (OpenWeatherMap / WeatherAPI / etc.)
• whether it’s a CLI or server (and any endpoint paths/flags)
• your crate dependencies (Cargo.toml)
