A content provider is responsible with interfacing with the environment and doing IO or what is required to supply content related with flows - isolating other libraries from the File SSystem or IO. It must implement the Provider trait

Required Methods

fn resolve_url( &self, url: &Url, default_name: &str, extensions: &[&str] ) -> Result<(Url, Option<Url>)>

Take a URL and uses it to determine a url where actual content can be read from using some provider specific logic. This may involve looking for default files in a directory (a file provider) or a server path (an http provider), or it may involve translating a library URL into a real on where content can be found.

fn get_contents(&self, url: &Url) -> Result<Vec<u8>>

Fetches content from a URL. It resolves the URL internally before attempting to fetch actual content
