Examples

Consider the following XML schema:

           <xs:element name="OnceSpecify" type="xs:int" minOccurs="1" />
           <xs:element name="TwiceOrMore" type="xs:int" minOccurs="2" maxOccurs="unbounded" />

   pub twice_or_more: Vec<i32>,
   pub any: AnyElement,
}

pub const BUILD_IN_ABSOLUTE_PATHS: Self

Use absolute paths for build-in types and traits.

Using this flag will instruct the generator to use absolute paths for build-in types and traits (e.g. usize, String or From) to avoid naming conflicts with generated types.

Examples

Consider the following XML schema:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
   xmlns:tns="http://example.com"

           <xs:any />
       </xs:sequence>
   </xs:complexType>
</xs:schema>

Enable the BUILD_IN_ABSOLUTE_PATHS feature only will result in the following code:

#[derive(Debug)]
pub struct MyChoiceType {
   pub content: MyChoiceTypeContent,
}
#[derive(Debug)]
pub enum MyChoiceTypeContent {
   Once(::core::primitive::i32),
   Optional(::core::option::Option<::core::primitive::i32>),
   OnceSpecify(::core::primitive::i32),
   TwiceOrMore(::std::vec::Vec<::core::primitive::i32>),
}
#[derive(Debug)]

   pub twice_or_more: ::std::vec::Vec<::core::primitive::i32>,
}

pub const ABSOLUTE_PATHS_INSTEAD_USINGS: Self

Use absolute paths instead of using directives for all non build-in types and traits.

Using this flag will instruct the generator to use absolute paths for non build-in and generated types and traits to avoid naming conflicts with other generated types.

This does not include build-in types (like usize, String or From), to use absolute paths for these also, you have to add the BUILD_IN_ABSOLUTE_PATHS as well.

impl Octal for GeneratorFlags

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PublicFlags for GeneratorFlags

type Primitive = u32

The type of the underlying storage.

type Internal = InternalBitFlags

The type of the internal field on the generated flags type.

impl Sub for GeneratorFlags

fn sub(self, other: Self) -> Self

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

type Output = GeneratorFlags

The resulting type after applying the - operator.

impl SubAssign for GeneratorFlags

fn sub_assign(&mut self, other: Self)

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

impl UpperHex for GeneratorFlags

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
