HTTP API engine for Exonum

exonum-api crate provides an extensible interface for building backend-agnostic HTTP APIs. Within Exonum, this crate is used by Rust services and in plugins for the Exonum node.

Under the hood exonum-api uses [actix].

Consult the crate docs for more details.

Examples

Providing HTTP API for a plugin:

```rust use exonumapi::{ApiBuilder}; use serdederive::{Deserialize, Serialize};

[derive(Serialize, Deserialize)]

pub struct SomeQuery { pub first: u64, pub second: u64, }

fn createapi() -> ApiBuilder { let mut builder = ApiBuilder::new(); builder .publicscope() .endpoint("some", |query: SomeQuery| { Ok(query.first + query.second) }); builder }

let builder = create_api(); // builder can now be passed to the node via plugin interface // or via node channel. ```

Usage

Include exonum-api as a dependency in your Cargo.toml:

toml [dependencies] exonum-api = "1.0.0"

Note that the crate rarely needs to be imported directly; it is re-exported by the exonum crate.
