Trait FromValue

pub trait FromValue<'a, 'input: 'a>: Sized {
    // Required method
    fn parse(
        node: SvgNode<'a, 'input>,
        aid: AId,
        value: &'a str,
    ) -> Option<Self>;
}

A trait for parsing attribute values.

Required Methods

fn parse(node: SvgNode<'a, 'input>, aid: AId, value: &'a str) -> Option<Self>

Parses an attribute value.

When None is returned, the attribute value will be logged as a parsing failure.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
