Struct Slug 

pub struct Slug(/* private fields */);

[A-Za-z0-9_-]+ — URL-safe identifier. Closes BUG-11.

Stored as TEXT. Use Slug::new(s) for user input, Slug::unchecked(s) for round-trips from already-validated sources (database, fixtures).

Implementations

impl Slug

pub fn new(s: impl Into<String>) -> Result<Self, ValidatorError>

Validate and wrap. Empty strings and any character outside [A-Za-z0-9_-] reject with ValidatorError::InvalidSlug.

pub fn unchecked(s: String) -> Self

Wrap without validation. Use only when the source is trusted (database round-trip, deterministic test fixtures).

pub fn as_str(&self) -> &str

pub fn into_inner(self) -> String

Trait Implementations

impl AsRef<str> for Slug

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Slug

fn clone(&self) -> Slug

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Slug

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

Formats the value using the given formatter.

impl<'r, DB: Database> Decode<'r, DB> for Slug

where String: Decode<'r, DB>,

fn decode(value: <DB as Database>::ValueRef<'r>) -> Result<Self, BoxDynError>

Decode a new value of this type using a raw value from the database.

impl<'de> Deserialize<'de> for Slug

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Slug

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

Formats the value using the given formatter.

impl<'q, DB: Database> Encode<'q, DB> for Slug

where String: Encode<'q, DB>,

fn encode_by_ref( &self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, BoxDynError>

Writes the value of self into buf without moving self.

fn encode( self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, Box<dyn Error + Sync + Send>>

where Self: Sized,

Writes the value of self into buf in the expected format for the database.

fn produces(&self) -> Option<<DB as Database>::TypeInfo>

fn size_hint(&self) -> usize

impl Eq for Slug

impl FromStr for Slug

type Err = ValidatorError

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 Slug

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 PartialEq for Slug

fn eq(&self, other: &Slug) -> 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 Serialize for Slug

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Slug

impl<DB: Database> Type<DB> for Slug

where String: Type<DB>,

fn type_info() -> DB::TypeInfo

Returns the canonical SQL type for this Rust type.

fn compatible(ty: &DB::TypeInfo) -> bool

Determines if this Rust type is compatible with the given SQL type.
