Implementations

impl NullKey

pub fn builder() -> Builder<Complete>

Returns a new builder.

impl NullKey

pub fn new() -> Self

Constructs a new instance of the type.

Trait Implementations

impl Clone for NullKey

fn clone(&self) -> NullKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NullKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NullKey

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl ErrorType for NullKey

fn code(&self) -> ErrorCode

Returns the error’s code.

fn name(&self) -> &str

Returns the error’s name.

fn instance_id(&self) -> Option<Uuid>

Returns the error’s instance ID, if it stores one.

fn safe_args(&self) -> &'static [&'static str]

Returns a sorted slice of the names of the error’s safe parameters.

fn with_instance_id(self, instance_id: Uuid) -> WithInstanceId<Self>

where Self: Sized,

Wraps the error in another that overrides its instance ID.

impl From<NullKey> for Builder<Complete>

fn from(v: NullKey) -> Self

Converts to this type from the input type.

impl Hash for NullKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for NullKey

fn cmp(&self, other: &NullKey) -> 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,

Restrict a value to a certain interval.

impl PartialEq for NullKey

fn eq(&self, other: &NullKey) -> 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 NullKey

fn partial_cmp(&self, other: &NullKey) -> 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.

impl Serialize for NullKey

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for NullKey

impl Eq for NullKey
