Crate xmlserde 

xmlserde is another tool for serializing and deserializing XML. It is designed for easy and clear use.

Please add these dependencies in your Cargo.toml.

xmlserde = "0.10"
xmlserde_derives = "0.10"

Deserialize

Suppose that XML struct is to be deserialized as below:

<person age="8">
    <name>Jeremy</name>
    <pet t="cat">Tom</pet>
    <pet t="dog">Spike</pet>
</person>

You can create a struct and derive the XmlDeserialize from xmlserde_derives, like:

use xmlserde_derives::XmlDeserialize;
#[derive(XmlDeserialize)]
pub struct Person {
    #[xmlserde(name = b"age", ty = "attr")]
    pub age: u16,
    #[xmlserde(name = b"pet", ty = "child")]
    pub pets: Vec<Pet>,
}

#[derive(XmlDeserialize)]
pub struct Pet {
    #[xmlserde(name = b"t", ty = "attr")]
    pub t: String,
    #[xmlserde(ty = "text")]
    pub name: String,
}

In xmlserde, you need to declare clearly that which tag and which type you are going to serde. Notice that it is a binary string for the name.

Serialize

As for serializing, you need to derive the XmlSerialize.

Enum

For attribute value

Please check in xml_serde_enum section.

For children element

You can define an enum like this.

#[derive(XmlSerialize, Deserialize)]
pub enum Pet{
    #[xmlserde(name = b"dog")]
    Dog(Dog),
    #[xmlserde(name = b"cat")]
    Cat(Cat),
}
pub struct Dog{}
pub struct Cat{}

In a field whose type is an enum, we can use ty = untag:

#[derive(XmlSerialize, Deserialize)]
pub struct Person {
    #[xmlserde(ty="untag")]
    pub pet: Pet,
}

In this case, Person can be serialized as

<person>
    <dog>
    ...
    </dog>
</person>

or

<person>
    <cat>
    ...
    </cat>
</person>

Attributes

• name: the tag of the XML element.
• vec_size: creating a vector with the given capacity before deserilizing a element lists. vec_size=4 or if your initial capacity is defined in an attr, you can use like this vec_size="cnt".
• default: assigning a parameter-free function to create a default value for a certain field. Notice that it requires the type of this value impls Eq and it will skip serializing when the value equals to the default one.
• untag: see the Enum above.

Examples

Please see LogiSheets for examples.

Re-exports

pub use quick_xml;

Macros

xml_serde_enum

A macro to help you create mappings between string values in XML and Rust enums.

Structs

Unparsed

Unparsed keeps the XML struct and will be serialized to XML with nothing change. It is helpful when you are debugging on deserializeing certain element.

Traits

XmlValue

Functions

xml_deserialize_from_reader

The entry for deserializing. T should have declared the root by #[xmlserde(root=b"")] to tell the deserializer which tag is the start for deserializing.

xml_deserialize_from_str

The entry for deserializing. T should have declared the root by #[xmlserde(root=b"")] to tell the deserializer which tag is the start for deserializing.

xml_serialize

The entry for serializing. T should have declared the root by #[xmlserde(root=b"")] to tell the serializer the tag name of the root.

xml_serialize_with_decl

The entry for serializing. T should have declared the root by #[xmlserde(root=b"")] to tell the serializer the tag name of the root. This function will add the header needed for a XML file.
