Using block fragments as part of larger template

[eliasgranse]

I am trying to use the feature called "block fragments" as described in the book, section "Block Segments". The block fragment I am trying to create is part of a larger template and the Rust code looks like this:

#[derive(Template)]
#[template(path = "pages/index.html", block = "my_block")]
pub struct MyTemplate {}

However the line #[derive(Template)] stops on the error:

unsupported attribute key Ident { ident: "block", span: #0 bytes(16214..16219) } found

Looking at the Docs.rs documentation this feature is not documented which makes me think this is not supported for some reason.

Anyways, I cannot seem to figure out what I am doing wrong. Thanks!

The block fragment feature hasn't been released yet. See #1035 for release planning -- you could use main for now.

I see thanks for responding so quickly!

I've just been tripped up by this as well. Perhaps don't include features in the book that don't actually exist yet, or at least a warning?
