Crate diagnostics_assertions

Utilities to assert the structure of a DiagnosticsHierarchy.

Pretty much the useful assert_data_tree macro plus some utilities for it.

Macros

• assert_data_tree
  Macro to simplify tree matching in tests. The first argument is the actual tree passed as a DiagnosticsHierarchyGetter (e.g. a DiagnosticsHierarchy or an Inspector). The second argument is given to tree_assertion! which creates a TreeAssertion to validate the tree.
• assert_json_diff
  Macro to check a hierarchy with a nice JSON diff. The syntax of the expected value is the same as that of hierarchy!, and essentially the same as assert_data_tree!, except that partial tree matching is not supported (i.e. the keyword contains).
• hierarchy
  This macro simplifies creating diagnostics hierarchies, to remove the need of writing multiple nested hierarchies and manually writing all properties.
• tree_assertion
  Macro to simplify creating TreeAssertions. Commonly used indirectly through the second parameter of assert_data_tree!. See assert_data_tree! for more usage examples.

Structs

• AnyBoolProperty
  A PropertyAssertion that passes for any Boolean.
• AnyBytesProperty
  A PropertyAssertion that passes for any Bytes.
• AnyDoubleProperty
  A PropertyAssertion that passes for any Double.
• AnyIntProperty
  A PropertyAssertion that passes for any Int.
• AnyNumericProperty
  A PropertyAssertion that passes for any Int, Uint, or Double.
• AnyProperty
  A PropertyAssertion that always passes
• AnyStringProperty
  A PropertyAssertion that passes for any String.
• AnyUintProperty
  A PropertyAssertion that passes for any Uint.
• DiagnosticsHierarchy
  A hierarchy of nodes representing structured data, such as Inspect or structured log data.
• HistogramAssertion
  An assertion for a histogram property.
• NonZeroIntProperty
  A PropertyAssertion that passes for non-zero, signed integers.
• NonZeroUintProperty
  A PropertyAssertion that passes for non-zero, unsigned integers.
• TreeAssertion
  Struct for matching against a Data tree (DiagnosticsHierarchy).

Traits

• DiagnosticsHierarchyGetter
  A type which can function as a “view” into a diagnostics hierarchy, optionally allocating a new instance to service a request.
• JsonGetter
• PropertyAssertion
  Trait implemented by types that can act as properies for assertion.

Functions
