Trait ParseBlock

    Send

    + ParseBlockClone {
    // Required methods
    fn parse(
        &self,
        arguments: TagTokenIter<'_>,
        block: TagBlock<'_, '_>,
        options: &Language,
    ) -> Result<Box<dyn Renderable>>;
    fn reflection(&self) -> &dyn BlockReflection;
}

A trait for creating custom custom block-size tags ({% if something %}{% endif %}). This is a simple type alias for a function.

This function will be called whenever the parser encounters a block and returns a new Renderable based on its parameters. The received parameters specify the name of the block, the argument Tokens passed to the block, a TagBlock inside the block and the global Language.

Required Methods

fn parse( &self, arguments: TagTokenIter<'_>, block: TagBlock<'_, '_>, options: &Language, ) -> Result<Box<dyn Renderable>>

fn reflection(&self) -> &dyn BlockReflection
