pub fn inspect(
    path: &Path,
    synth: &SynthArg,
    opts: &DescribeOptions,
) -> Result<String, PresetError>

The text preset inspect prints: the header fields of the adapter, a blank line, then the decoded tree.

Errors

A PresetError when the synth cannot be resolved, the file cannot be read or it is not a valid preset.
