Enum bindgen::callbacks::ImplementsTrait

pub enum ImplementsTrait {
    Yes,
    Manually,
    No,
}

Whether it is possible or not to automatically derive trait for an item.

        No
         ^
         |
     Manually
         ^
         |
        Yes

Initially we assume that we can derive trait for all types and then update our understanding as we learn more about each type.

Variants

Yes

Yes, we can derive automatically.

Manually

The only thing that stops us from automatically deriving is that array with more than maximum number of elements is used.

This means we probably can “manually” implement such trait.

No

No, we cannot.

Implementations

impl CanDerive

pub fn join(self, rhs: Self) -> Self

Take the least upper bound of self and rhs.

Trait Implementations

impl BitOr for CanDerive

type Output = CanDerive

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self::Output

Performs the | operation.

impl BitOrAssign for CanDerive

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl Clone for CanDerive

fn clone(&self) -> CanDerive

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CanDerive

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

Formats the value using the given formatter.

impl Default for CanDerive

fn default() -> CanDerive

Returns the “default value” for a type.

impl Ord for CanDerive

fn cmp(&self, other: &CanDerive) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for CanDerive

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

impl PartialOrd for CanDerive

fn partial_cmp(&self, other: &CanDerive) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
