Enum Flattened 

pub enum Flattened {
    Html(String),
    Deferred(Vec<Segment>),
}

What flattening produced. Both variants are normal outcomes — Deferred means callback nodes are present and need splicing — so this is an enum rather than a Result.

Variants

Html(String)

Deferred(Vec<Segment>)

Implementations

impl Flattened

pub fn into_html(self) -> Option<String>

The finished markup, or None when callback nodes still need splicing. Handy where the caller knows no callback rules exist. (Only test code needs it today, but it’s part of the shape the extracted crates will expose.)
