Function plugin_from_operation_fn

pub fn plugin_from_operation_fn<F>(f: F) -> OperationFn<F>

Constructs a Plugin using a closure over the [ServiceShape::] F: Fn(ShapeId, T) -> Service`.

Example

use aws_smithy_http_server::plugin::plugin_from_operation_fn;
use tower::layer::layer_fn;

struct FooService<S> {
    info: String,
    inner: S
}

fn map<S>(op: Operation, inner: S) -> FooService<S> {
    match op {
        Operation::CheckHealth => FooService { info: op.shape_id().name().to_string(), inner },
        Operation::GetPokemonSpecies => FooService { info: "bar".to_string(), inner },
        _ => todo!()
    }
}

// This plugin applies the `FooService` middleware around every operation.
let plugin = plugin_from_operation_fn(map);
