Struct Options 

#[non_exhaustive]
pub struct Options {
    pub target: Triple,
    pub opt_level: OptLevel,
    pub emit: EmitKind,
    pub debug_info: bool,
    pub warnings_are_errors: bool,
    pub error_limit: u32,
}

Everything a compilation was asked to do.

Options are a plain value with no interior mutability, so a caller can build one, clone it, tweak one field and run a second compilation, which is exactly what the differential testing in spec/15-testing.md needs.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

target: Triple

The target to generate code for.

opt_level: OptLevel

The optimisation level.

emit: EmitKind

What to produce.

debug_info: bool

Whether to emit debug information.

warnings_are_errors: bool

Whether warnings are errors.

error_limit: u32

How many diagnostics to print before giving up. Past a certain point the output is noise from a single earlier mistake, and GCC’s default of no limit is not a kindness.
