Struct OutputOptions

Source

struct OutputOptions {
    format: MessageFormat,
    cache_cell: Option<(PathBuf, LazyCell<File>)>,
    show_diagnostics: bool,
    warnings_seen: usize,
    errors_seen: usize,
}

Expand description

Configuration of the display of messages emitted by the compiler, e.g. diagnostics, warnings, errors, and message caching.

Fields§

§format: MessageFormat

What format we’re emitting from Cargo itself.

§cache_cell: Option<(PathBuf, LazyCell<File>)>

Where to write the JSON messages to support playback later if the unit is fresh. The file is created lazily so that in the normal case, lots of empty files are not created. If this is None, the output will not be cached (such as when replaying cached messages).

§show_diagnostics: bool

If true, display any diagnostics. Other types of JSON messages are processed regardless of the value of this flag.

This is used primarily for cache replay. If you build with -vv, the cache will be filled with diagnostics from dependencies. When the cache is replayed without -vv, we don’t want to show them.

§warnings_seen: usize

Tracks the number of warnings we’ve seen so far.

§errors_seen: usize

Tracks the number of errors we’ve seen so far.
