Trait tough::schema::Transport

pub trait Transport: Debug + DynClone {
    // Required method
    fn fetch(
        &self,
        url: Url
    ) -> Result<Box<dyn Read + Send + '_>, TransportError>;
}

A trait to abstract over the method/protocol by which files are obtained.

The trait hides the underlying types involved by returning the Read object as a Box<dyn Read + Send> and by requiring concrete type TransportError as the error type.

Inclusion of the DynClone trait means that you will need to implement Clone when implementing a Transport.

Required Methods

fn fetch(&self, url: Url) -> Result<Box<dyn Read + Send + '_>, TransportError>

Opens a Read object for the file specified by url.
