We default to 1 here since we want to behave like a sequential compiler for now. This’ll likely be adjusted in the future. Note that -Zthreads=0 is the way to get the num_cpus behavior.

This name is kind of confusing: Most unstable options enable something themselves, while this just allows “normal” options to be feature-gated.

Implementations

impl UnstableOptions

pub fn diagnostic_handler_flags(&self, can_emit_warnings: bool) -> HandlerFlags

impl UnstableOptions

pub fn build(matches: &Matches, error_format: ErrorOutputType) -> UnstableOptions

fn dep_tracking_hash(
    &self,
    for_crate_hash: bool,
    error_format: ErrorOutputType
) -> u64

Trait Implementations

impl Clone for UnstableOptions

fn clone(&self) -> UnstableOptions

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for UnstableOptions

fn default() -> UnstableOptions

Returns the “default value” for a type.

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.
