Enum Assign 

pub enum Assign {
    Ok,
    OkUnsafe,
    Narrowing,
    IntAsEnum,
    No,
}

The outcome of is_assignable — richer than a bool so the caller can raise the right diagnostic (Playbook §3.5/§5).

Variants

Ok

Cleanly assignable.

OkUnsafe

Assignable, but the source is Variant — a gradual (unchecked) escape.

Narrowing

float stored into an int slot (NARROWING_CONVERSION).

IntAsEnum

int used where an enum is expected (INT_AS_ENUM_WITHOUT_CAST).

No

Not assignable (TYPE_MISMATCH).

Trait Implementations

impl Clone for Assign

fn clone(&self) -> Assign

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Assign

impl Debug for Assign

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

Formats the value using the given formatter.

impl Eq for Assign

impl PartialEq for Assign

fn eq(&self, other: &Assign) -> 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.
