Struct validus::vstrext::Conj

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

Require both rules to pass, from left to right.

See also:

• Disj (dual).
• EitherError (error type).

Example

use validus::prelude::*;

// Length limit and ASCII only.
pub type UserNameRule = Conj<StringSizeRule<4, 12>, StringAsciiRule>;

let bad1 = "123".validate::<UserNameRule>();
assert!(bad1.is_err());
assert!(bad1.unwrap_err().is_left()); // left = length limit

let bad2 = "1234567890123".validate::<UserNameRule>();
assert!(bad2.is_err());
assert!(bad2.unwrap_err().is_left()); // left

let bad3 = "wow 😎".validate::<UserNameRule>();
assert!(bad3.is_err());
assert!(bad3.unwrap_err().is_right()); // right = ASCII only

let good = "1234".validate::<UserNameRule>();
assert!(good.is_ok());
assert_eq!(good.unwrap(), "1234");

Trait Implementations

impl<L: Clone + ValidateString, R: Clone + ValidateString> Clone for Conj<L, R>

fn clone(&self) -> Conj<L, R>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<L: Debug + ValidateString, R: Debug + ValidateString> Debug for Conj<L, R>

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

Formats the value using the given formatter.

impl<L: Default + ValidateString, R: Default + ValidateString> Default for Conj<L, R>

fn default() -> Conj<L, R>

Returns the “default value” for a type.

impl<L: Hash + ValidateString, R: Hash + ValidateString> Hash for Conj<L, 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<L: Ord + ValidateString, R: Ord + ValidateString> Ord for Conj<L, R>

fn cmp(&self, other: &Conj<L, 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<L: PartialEq + ValidateString, R: PartialEq + ValidateString> PartialEq<Conj<L, R>> for Conj<L, R>

fn eq(&self, other: &Conj<L, 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<L: PartialOrd + ValidateString, R: PartialOrd + ValidateString> PartialOrd<Conj<L, R>> for Conj<L, R>

fn partial_cmp(&self, other: &Conj<L, 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<L: ValidateString, R: ValidateString> ValidateString for Conj<L, R>

type Error = EitherError<<L as ValidateString>::Error, <R as ValidateString>::Error>

Explain why the string slice is invalid.

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

Validate a string slice.
