Functions

```
fpromise::promise<std::vector<std::string>> ReadAllChildNames (TreeNameIteratorClient & iter)
```
Collect all of the names of the children of the `Inspector` managed by the tree server

which started the TreeNameIterator server. Essentially, it drains the iterator.

```
fpromise::promise<Hierarchy> ReadFromTree (TreeClient & tree, async_dispatcher_t * dispatcher)
```
Turn a Tree handle into a complete hierarchy, including lazy children/values.

This function uses `ZX_ASSERT` if it encounters FIDL errors.

```
::testing::Matcher<const NodeValue &> NameMatches (std::string name)
```
Matches against the name of an Inspect Node.

Example:

EXPECT_THAT(node, NameMatches("objects"));

Defined at line 123 of file ../../sdk/lib/inspect/testing/cpp/inspect.cc
```
::testing::Matcher<const NodeValue &> PropertyList (PropertiesMatcher matcher)
```
Matches against the property list of an Inspect Node.

Example:

EXPECT_THAT(node, AllOf(PropertyList(::testing::IsEmpty())));

template <typename T>
```
```
size_t ComputeLinearBucketIndex (T floor, T step_size, size_t total_buckets, T value)
```
Computes the bucket index for a value in a linear histogram.

|total_buckets| is the number of buckets initially defined when the histogram

property was created plus 2 (overflow and underflow).

template <typename T>
```
```
size_t ComputeExponentialBucketIndex (T floor, T initial_step, T step_multiplier, size_t total_buckets, T value)
```
Computes the bucket index for a value in an exponential histogram.

|total_buckets| is the number of buckets initially defined when the histogram

property was created plus 2 (overflow and underflow).
