/// Whether the mapping should be high-resolution.
/// Hi-res mappings map every single character, meaning (for example) your devtools will always
/// be able to pinpoint the exact location of function calls and so on.
/// With lo-res mappings, devtools may only be able to identify the correct
/// line - but they're quicker to generate and less bulky.
/// You can also set `"boundary"` to generate a semi-hi-res mappings segmented per word boundary
/// instead of per character, suitable for string semantics that are separated by words.
/// If sourcemap locations have been specified with s.addSourceMapLocation(), they will be used here.
