• Bump the serde_json dependency to ^1.0.17, which solves the JSON matcher problems when the preserve_order feature of serde_json is enabled.

Thanks to @Diggsey

• Fixed compiler warnings because of useless mut.

Thanks to @jean553

• Introduced the Matcher::JSON variant for matching JSON request bodies.

Thanks to @andir

• Fixed a bug where tests wouldn't run without the --test-threads=1 flag any more.

• Fixed a bug where the status reason phrase was missing from the server response. This was causing problems with mocking requests that went through Hyper.

• Rewrote part of the internal implementation of Mockito, replacing the client/server approach with a singleton state controlled through a mutex. Long story short, this removed the need for curl and serde as dependencies and significantly improved the response time.

• The Mock#assert error message now prints out the last unmatched request as well:

  Expected 1 request(s) to:
  
  POST /users
  bob
  
  ...but received 0
  
  The last unmatched request was:
  
  POST /users
  content-length: 5
  alice
  

• Turned request headers into Vec, instead of HashMap to solve the sorting problem once and for all.
• Namespaced the internal API with /mockito.

• Introduced the Mock#match_body method for matching the request body by using the usual Matcher variants.

• Introduced the Mock#assert method to assert that a mock was called. You can use Mock#expect to specify the number of requests you're expecting. Check the docs for more details.
• [Breaking] Mocks will be automatically cleaned up whenever their lifetime ends. This is the more Rusty approach to having to call Mock#remove or reset explicitly. You'll want to assign your mock to a variable in order to establish its lifetime. Check the docs for examples.
• [Breaking] The Mock#remove method has been removed (or better said, it's private now). You can use std::mem::drop if you really need to remove a mock before its lifetime ends.
• [Breaking] The Mock#create_for method has been removed. Normal Rust closures { ... } and the lifetimes should replace this just fine.
• [Breaking] Builder-pattern methods of the Mock struct are now returning Mock instead of &mut Mock.
• Established clearer boundries between the mock server and the mock client.

• Introduce a new matcher: Match::Regex(String), for matching the request path or headers with a regular expression.
• Extend the matcher logic to matching the request path (supports all matchers now).
• Fix a bug in the request processing for large bodies.
