Enum PatternItemCow

pub enum PatternItemCow<'a, T> {
    Placeholder(T),
    Literal(Cow<'a, str>),
}

A borrowed-or-owned item in a Pattern. Items are either string literals or placeholders.

✨ Enabled with the alloc Cargo feature.

Variants

Placeholder(T)

A placeholder of the type specified on this PatternItemCow.

Literal(Cow<'a, str>)

A string literal. This can occur in one of three places:

1. Between the start of the string and the first placeholder (prefix)
2. Between two placeholders (infix)
3. Between the final placeholder and the end of the string (suffix)

Trait Implementations

impl<'a, T: Clone> Clone for PatternItemCow<'a, T>

fn clone(&self) -> PatternItemCow<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug> Debug for PatternItemCow<'a, T>

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

Formats the value using the given formatter.

impl<'de: 'a, 'a, T> Deserialize<'de> for PatternItemCow<'a, T>

where T: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a, K> From<ParsedPatternItem<'a, K>> for PatternItemCow<'a, K>

fn from(value: ParsedPatternItem<'a, K>) -> Self

Converts to this type from the input type.

impl<'a, T, U> From<PatternItem<'a, U>> for PatternItemCow<'a, T>

where T: From<U>,

fn from(value: PatternItem<'a, U>) -> Self

Converts to this type from the input type.

impl<'a, T: Ord> Ord for PatternItemCow<'a, T>

fn cmp(&self, other: &PatternItemCow<'a, T>) -> 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<'a, T: PartialEq> PartialEq for PatternItemCow<'a, T>

fn eq(&self, other: &PatternItemCow<'a, T>) -> 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<'a, T: PartialOrd> PartialOrd for PatternItemCow<'a, T>

fn partial_cmp(&self, other: &PatternItemCow<'a, T>) -> 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<'a, T> Serialize for PatternItemCow<'a, T>

where T: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
