Struct validus::vstrext::Neg

#[repr(transparent)]
pub struct Neg<R: ValidateString> { /* private fields */ }

Require the rule to NOT pass.

If the rule doesn’t pass, discard the error.

If the rule passes, raise the error NegationPassedError, which contains no information.

Trait Implementations

impl<R: Clone + ValidateString> Clone for Neg<R>

fn clone(&self) -> Neg<R>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<R: Debug + ValidateString> Debug for Neg<R>

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

Formats the value using the given formatter.

impl<R: Default + ValidateString> Default for Neg<R>

fn default() -> Neg<R>

Returns the “default value” for a type.

impl<R: Hash + ValidateString> Hash for Neg<R>

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<R: Ord + ValidateString> Ord for Neg<R>

fn cmp(&self, other: &Neg<R>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<R: PartialEq + ValidateString> PartialEq<Neg<R>> for Neg<R>

fn eq(&self, other: &Neg<R>) -> 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<R: PartialOrd + ValidateString> PartialOrd<Neg<R>> for Neg<R>

fn partial_cmp(&self, other: &Neg<R>) -> 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.

impl<R: ValidateString> ValidateString for Neg<R>

type Error = NegationPassedError

Explain why the string slice is invalid.

fn validate_str(s: &str) -> Result<(), Self::Error>

Validate a string slice.
