Function aws_smithy_http_server::plugin::plugin_from_operation_name_fn

pub fn plugin_from_operation_name_fn<L, F>(f: F) -> OperationNameFn<F>where
    F: Fn(&'static str) -> L,

Constructs a Plugin using a closure over the operation name F: Fn(&'static str) -> L where L is a HTTP Layer.

Example

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

// A `Service` which prints the operation name before calling `S`.
struct PrintService<S> {
    operation_name: &'static str,
    inner: S
}

// A `Layer` applying `PrintService`.
struct PrintLayer {
    operation_name: &'static str
}

// Defines a closure taking the operation name to `PrintLayer`.
let f = |operation_name| PrintLayer { operation_name };

// This plugin applies the `PrintService` middleware around every operation.
let plugin = plugin_from_operation_name_fn(f);
