Trait xso::FromXml

pub trait FromXml: Sized {
    // Required methods
    fn from_tree(tree: Element) -> Result<Self, Error>;
    fn absent() -> Option<Self>;
}

Provide construction of structs from XML (sub-)trees.

This trait is what is really implemented by the FromXml derive macro.

Required Methods

fn from_tree(tree: Element) -> Result<Self, Error>

Convert an XML subtree into a struct or fail with an error.

fn absent() -> Option<Self>

Provide an optional default if the element is absent.

This is used to automatically make Option<T> default to None.

Object Safety

This trait is not object safe.
