Enum rustc_session::config::Polonius

pub enum Polonius {
    Off,
    Legacy,
    Next,
}

-Zpolonius values, enabling the borrow checker polonius analysis, and which version: legacy, or future prototype.

Variants

Off

The default value: disabled.

Legacy

Legacy version, using datalog and the polonius-engine crate. Historical value for -Zpolonius.

Next

In-tree prototype, extending the NLL infrastructure.

Implementations

impl Polonius

pub fn is_legacy_enabled(&self) -> bool

Returns whether the legacy version of polonius is enabled

pub fn is_next_enabled(&self) -> bool

Returns whether the “next” version of polonius is enabled

Trait Implementations

impl Clone for Polonius

fn clone(&self) -> Polonius

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Polonius

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Polonius

fn default() -> Polonius

Returns the “default value” for a type.

impl DepTrackingHash for Polonius

fn hash( &self, hasher: &mut DefaultHasher, _: ErrorOutputType, _for_crate_hash: bool )

impl Hash for Polonius

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Polonius

fn eq(&self, other: &Polonius) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Polonius

impl StructuralPartialEq for Polonius
