Trait LinkExpander 

pub trait LinkExpander: Send + Sync {
    // Required methods
    fn enabled(&self, config: &BabyriteConfig) -> bool;
    fn expand_all<'life0, 'life1, 'life2, 'async_trait>(
        &'life0 self,
        cx: &'life1 ExpandContext<'life2>,
    ) -> Pin<Box<dyn Future<Output = Vec<ExpandedContent>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait,
             'life2: 'async_trait;
}

A link expander: parses its own link type out of a message and expands each link into ExpandedContent.

Adding a new link type means implementing this trait and registering the expander in EXPANDERS; the event handler needs no changes.

Required Methods

fn enabled(&self, config: &BabyriteConfig) -> bool

Whether this expander is enabled under config.

fn expand_all<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, cx: &'life1 ExpandContext<'life2>, ) -> Pin<Box<dyn Future<Output = Vec<ExpandedContent>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Parses and expands all links of this expander’s type in the message.

Failures are logged per link and never abort the other links or expanders, so this returns only the successful expansions.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
