struct-field-names-as-array

Provides the FieldNamesAsArray procedural macro.

The procedural macro adds the FIELD_NAMES_AS_ARRAY constant to the struct. The FIELD_NAMES_AS_ARRAY is an array containing the field names of the struct (as the name suggests). The visibility of the FIELD_NAMES_AS_ARRAY is the same as the corresponding struct.

NOTE: the macro can only be derived by named structs.

Example

```rust use structfieldnamesasarray::FieldNamesAsArray;

[derive(FieldNamesAsArray)]

struct Foo { bar: String, baz: String, bat: String, }

asserteq!(Foo::FIELDNAMESASARRAY, ["bar", "baz", "bat"]); ```

Attributes

The FieldNamesAsArray macro supports the field_names_as_array attribute with the following possible arguments:

• skip: do not add the field to FIELD_NAMES_AS_ARRAY

  Example

  ```rust use structfieldnamesasarray::FieldNamesAsArray;

  [derive(FieldNamesAsArray)]

  struct Foo { bar: String, baz: String,

  [fieldnamesas_array(skip)]

  bat: String, }

  asserteq!(Foo::FIELDNAMESASARRAY, ["bar", "baz"]); ```
