Function launch
Sourcepub fn launch(pipeline_description: &str) -> Result<Element, Error>Expand description
Create a new pipeline based on command line syntax.
Please note that you might get a return value that is not None even though
the error is set. In this case there was a recoverable parsing error and you
can try to play the pipeline.
To create a sub-pipeline (bin) for embedding into an existing pipeline
use [parse_bin_from_description()][crate::parse_bin_from_description()].
§pipeline_description
the command line describing the pipeline
§Returns
a new element on success, None on
failure. If more than one toplevel element is specified by the
pipeline_description, all elements are put into a Pipeline, which
than is returned.
