Struct TagComponent 

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

Represents both tag names and values (see TagName & TagValue).

See the TagComponent::from associated method for information on what constitutes a valid tag name/value.

Implementations

impl TagComponent

pub fn from<S: ToString>(value: &S) -> Result<Self, TagError>

Create a TagComponent, or return a TagError

First the input string is converted to lowercase and leading and trailing whitespace is removed

What is left:

• Must only contain lowercase ASCII letters or -s
• Must not start with -
• Must not end with -
• Must not contain consecutive hyphens

Valid inputs

• My-tag
• tag-component-here

Invalid inputs

• -my-tag
• another-tag-
• tag--component

pub fn as_str(&self) -> &str

Borrow the underlying

Trait Implementations

impl Clone for TagComponent

fn clone(&self) -> TagComponent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TagComponent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TagComponent

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TagComponent

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

Formats the value using the given formatter.

impl Hash for TagComponent

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 Ord for TagComponent

fn cmp(&self, other: &TagComponent) -> 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 PartialEq for TagComponent

fn eq(&self, other: &TagComponent) -> 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 PartialOrd for TagComponent

fn partial_cmp(&self, other: &TagComponent) -> 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 Serialize for TagComponent

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for TagComponent
