Enum ReturnShape 

#[non_exhaustive]
pub enum ReturnShape {
    Bool,
    String,
    Float,
    Int,
    Contextual,
}

Return shape produced by a standard-library rule.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Bool

Boolean result.

String

String result.

Float

Floating-point result.

Int

Integer result.

Contextual

Type is supplied by call-site context.

Trait Implementations

impl Clone for ReturnShape

fn clone(&self) -> ReturnShape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ReturnShape

impl Debug for ReturnShape

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

Formats the value using the given formatter.

impl Eq for ReturnShape

impl PartialEq for ReturnShape

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