Struct StartsWith

pub struct StartsWith<S: TypeStr + ?Sized> { /* private fields */ }

Checks if the string starts with the specified prefix S.

Trait Implementations

impl<S: Clone + TypeStr + ?Sized> Clone for StartsWith<S>

fn clone(&self) -> StartsWith<S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug + TypeStr + ?Sized> Debug for StartsWith<S>

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

Formats the value using the given formatter.

impl<S: Default + TypeStr + ?Sized> Default for StartsWith<S>

fn default() -> StartsWith<S>

Returns the “default value” for a type.

impl<S: Hash + TypeStr + ?Sized> Hash for StartsWith<S>

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<S: Ord + TypeStr + ?Sized> Ord for StartsWith<S>

fn cmp(&self, other: &StartsWith<S>) -> 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<S: PartialEq + TypeStr + ?Sized> PartialEq for StartsWith<S>

fn eq(&self, other: &StartsWith<S>) -> 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<S: PartialOrd + TypeStr + ?Sized> PartialOrd for StartsWith<S>

fn partial_cmp(&self, other: &StartsWith<S>) -> 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<T: AsRef<str> + ?Sized, S: TypeStr + ?Sized> Predicate<T> for StartsWith<S>

type Error = StartsWithError

The associated error type which is used to represent checks.

fn check(value: &T) -> Result<(), Self::Error>

Checks if the value of type T satisfies the predicate.

fn expect(formatter: &mut Formatter<'_>) -> Result

Formats the expectation of the predicate.

fn expected() -> Expected<T, Self>

Returns Expected type that uses expect to implement the fmt::Display trait, allowing to format errors without depending on std or alloc.

impl<S: Eq + TypeStr + ?Sized> Eq for StartsWith<S>

impl<S: TypeStr + ?Sized> StructuralPartialEq for StartsWith<S>
