Enum MagicSetsMode 

pub enum MagicSetsMode {
    Auto,
    On,
    Off,
}

Magic-set rewrite mode for bound recursive deterministic queries.

Variants

Auto

Apply the rewrite when the compiler can prove the supported safe subset.

On

Require the rewrite and fail with a typed diagnostic if it is unsafe.

Off

Disable magic-set rewriting.

Trait Implementations

impl Clone for MagicSetsMode

fn clone(&self) -> MagicSetsMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MagicSetsMode

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

Formats the value using the given formatter.

impl PartialEq for MagicSetsMode

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

Tests for self and other values to be equal, and is used by ==.

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

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