Struct MockSender

pub struct MockSender { /* private fields */ }

Implementations

impl MockSender

An RpcSender used for unit testing RpcClient.

This is primarily for internal use.

Unless directed otherwise, it will generally return a reasonable default response, at least for RpcRequest values for which responses have been implemented.

The behavior can be customized in two ways:

1. The url constructor argument is not actually a URL, but a simple string directive that changes MockSenders behavior in specific scenarios.

   If url is “fails” then any call to send will return Ok(Value::Null).

   It is customary to set the url to “succeeds” for mocks that should return successfully, though this value is not actually interpreted.

   Other possible values of url are specific to different RpcRequest values. Read the implementation for specifics.

2. Custom responses can be configured by providing Mocks to the MockSender::new_with_mocks constructor. This type is a HashMap from RpcRequest to a JSON Value response, Any entries in this map override the default behavior for the given request.

pub fn new<U: ToString>(url: U) -> Self

pub fn new_with_mocks<U: ToString>(url: U, mocks: Mocks) -> Self

pub fn new_with_mocks_map<U: ToString>(url: U, mocks: MocksMap) -> Self
