Struct protobuf::EnumOrUnknown

pub struct EnumOrUnknown<E> { /* private fields */ }

Protobuf enums with possibly unknown values are preserved in this struct.

Implementations

impl<E> EnumOrUnknown<E>

pub const fn from_i32(value: i32) -> EnumOrUnknown<E>

Construct from any i32 value.

Note passed value is not required to be a valid enum value.

impl<E: Enum> EnumOrUnknown<E>

pub fn new(e: E) -> EnumOrUnknown<E>

Construct from typed enum

pub fn value(&self) -> i32

Get contained i32 value of enum

pub fn enum_value(&self) -> Result<E, i32>

Get i32 value as typed enum. Return None is value is unknown.

pub fn unwrap(&self) -> E

Get contained enum, panic if value is unknown.

pub fn enum_value_or_default(&self) -> E

Get i32 value as typed enum. Return default enum value (first value) if value is unknown.

pub fn enum_value_or(&self, map_unknown: E) -> E

Get i32 value as typed enum. Return given enum value if value is unknown.

impl<E: EnumFull> EnumOrUnknown<E>

pub fn enum_descriptor() -> EnumDescriptor

Get enum descriptor by type.

Trait Implementations

impl<E: Clone> Clone for EnumOrUnknown<E>

fn clone(&self) -> EnumOrUnknown<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Enum + Debug> Debug for EnumOrUnknown<E>

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

Formats the value using the given formatter.

impl<E: Enum> Default for EnumOrUnknown<E>

fn default() -> EnumOrUnknown<E>

Returns the “default value” for a type.

impl<E: Enum> From<E> for EnumOrUnknown<E>

fn from(e: E) -> Self

Converts to this type from the input type.

impl<E: Ord> Ord for EnumOrUnknown<E>

fn cmp(&self, other: &EnumOrUnknown<E>) -> 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<E: PartialEq> PartialEq for EnumOrUnknown<E>

fn eq(&self, other: &EnumOrUnknown<E>) -> 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<E: PartialOrd> PartialOrd for EnumOrUnknown<E>

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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