Thanks for the PR!

A few things:

1. Can you run cargo fmt? That will clear up the CI errors.
2. Can you add a test?
3. Do you need access to the content of the wrapper? I noticed you're using exec_with_no_result but still declaring the wrapper in your responses. This might be an additional request to allow access to the wrapper if that's what you're after.

@jmgilman Please review.

Thanks for your Pull request, and sorry for the delay.
It would be nice if you can add the complete identity secret engine, so we provide a feature complete implementation for it.

[Haennetz]

Please name the folder identity instead of entity for the entity we can use separated modules like this auth

[Haennetz]

Please add some Comments above your function for example.

Suggested change

	/// ## Create Entity
	/// This endpoint creates an entity.
	///
	/// * Path: /identity/entity
	/// * Method: POST
	/// * Response: [CreateEntityResponse]
	/// * Reference: https://www.vaultproject.io/api-docs/dentity/entity#create-an-entity

[Haennetz]

We should add a full feature set of the API documentation for the endpoint.

Suggested change

	pub struct CreateEntityRequest {
	pub name: String,
	pub policies: String,
	}
	pub struct CreateEntityRequest {
	pub name: String,
	pub id: Option<String>,
	pub metadata: Option<HashMap<String, String>>,
	pub policies: Option<Vec<String>>,
	pub disabled: Option<bool>,
	}

lease_dorations are always positive seconds, so we should use u64

Suggested change

	pub lease_duration: i64,
	pub lease_duration: u64,

@is-atw do you have time and motivation to apply the suggested changes?
If not maybe we can switch to #64 , @slck seems to have implemented more or less the same features
