+# NNAPI Conversions
+
+`convert` fails if either the source type or the destination type is invalid, and it yields a valid
+object if the conversion succeeds. For example, let's say that an enumeration in the current
+version has fewer possible values than the "same" canonical enumeration, such as `OperationType`.
+The new value of `HARD_SWISH` (introduced in Android R / NN HAL 1.3) does not map to any valid
+existing value in `OperationType`, but an older value of `ADD` (introduced in Android OC-MR1 / NN
+HAL 1.0) is valid. This can be seen in the following model conversions:
+
+```cpp
+// Unsuccessful conversion
+const nn::Model canonicalModel = createModelWhichHasV1_3Operations();
+const nn::Result<V1_0::Model> maybeVersionedModel = V1_0::utils::convert(canonicalModel);
+EXPECT_FALSE(maybeVersionedModel.has_value());
+```
+```cpp
+// Successful conversion
+const nn::Model canonicalModel = createModelWhichHasOnlyV1_0Operations();
+const nn::Result<V1_0::Model> maybeVersionedModel = V1_0::utils::convert(canonicalModel);
+ASSERT_TRUE(maybeVersionedModel.has_value());
+const V1_0::Model& versionedModel = maybeVersionedModel.value();
+EXPECT_TRUE(V1_0::utils::valid(versionedModel));
+```
+
+`V1_X::utils::convert` does not guarantee that all information is preserved. For example, In the
+case of `nn::ErrorStatus`, the new value of `MISSED_DEADLINE_TRANSIENT` can be represented by the
+existing value of `V1_0::GENERAL_FAILURE`:
+
+```cpp
+// Lossy Canonical -> HAL -> Canonical conversion
+const nn::ErrorStatus canonicalBefore = nn::ErrorStatus::MISSED_DEADLINE_TRANSIENT;
+const V1_0::ErrorStatus versioned = V1_0::utils::convert(canonicalBefore).value();
+const nn::ErrorStatus canonicalAfter = nn::convert(versioned).value();
+EXPECT_NE(canonicalBefore, canonicalAfter);
+```
+
+However, `nn::convert` is guaranteed to preserve all information:
+
+```cpp
+// Lossless HAL -> Canonical -> HAL conversion
+const V1_0::ErrorStatus versionedBefore = V1_0::ErrorStatus::GENERAL_FAILURE;
+const nn::ErrorStatus canonical = nn::convert(versionedBefore).value();
+const V1_0::ErrorStatus versionedAfter = V1_0::utils::convert(canonical).value();
+EXPECT_EQ(versionedBefore, versionedAfter);
+```
+
+The `convert` functions operate only on types that used in a HIDL method call directly. The
+`unvalidatedConvert` functions operate on types that are either used in a HIDL method call directly
+(i.e., not as a nested class) or used in a subsequent version of the NN HAL. Prefer using `convert`
+over `unvalidatedConvert`.
