Struct sudoku_backend::ops::constraints::EMail

pub struct EMail(pub String);

Weakly validate the string to be roughly e-mail-shaped.

Examples

assert_eq!(EMail::from_str("nabijaczleweli@gmail.com"),
           Ok(EMail("nabijaczleweli@gmail.com".to_string())));

assert!(EMail::from_str("Давай пойдём в Москву!").is_err());

Trait Implementations

impl PartialEq<EMail> for EMail

fn eq(&self, other: &EMail) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &EMail) -> bool

This method tests for !=.

impl Clone for EMail

fn clone(&self) -> EMail

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Ord for EMail

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

impl Eq for EMail

impl PartialOrd<EMail> for EMail

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

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

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

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

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

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

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

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

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

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

impl Debug for EMail

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

Formats the value using the given formatter.

impl FromStr for EMail

type Err = Self::Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for EMail

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,

Feeds a slice of this type into the given [Hasher].

impl Serialize for EMail

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

Serialize this value into the given Serde serializer.

impl<'de> Deserialize<'de> for EMail

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where     __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'v> FromFormValue<'v> for EMail

type Error = Option<&'static str>

The associated error which can be returned from parsing. It is a good idea to have the return type be or contain an &'v str so that the unparseable string can be examined after a bad parse.

fn from_form_value(form_value: &'v RawStr) -> Result<Self, Self::Error>

Any deeper kind of validation is either too complex or too bad to be reliable.

This, while not providing much guarantee, at least enforces something resemblant of an e-mail address.

fn default() -> Option<Self>

Returns a default value to be used when the form field does not exist. If this returns None, then the field is required. Otherwise, this should return Some(default_value). The default implementation simply returns None.
