Struct cargo::core::compiler::OutputOptions

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

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.

Implementations

impl OutputOptions

fn new(cx: &Context<'_, '_>, unit: &Unit) -> OutputOptions

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
