Enum ComponentRef

pub enum ComponentRef<'a> {
    Crate(&'a str),
    Str(&'a str),
    Id(usize),
}

A reference to a component of an item.

All indexes refer to sibling indexes. So two sibling id components could have the indexes 1 and 2 respectively.

Variants

Crate(&'a str)

A crate string component.

Str(&'a str)

A regular string component.

Id(usize)

A nested anonymous part with an identifier.

Implementations

impl<'a> ComponentRef<'a>

pub fn as_str(&self) -> Option<&'a str>

pub fn id(self) -> Option<usize>

Get the identifier of the component if it is an identifier component.

pub fn to_owned(&self) -> Result<Component>

Formats the value using the given formatter.

impl<'de: 'a, 'a> Deserialize<'de> for ComponentRef<'a>

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ComponentRef<'_>

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

Formats the value using the given formatter.

impl<'a> Hash for ComponentRef<'a>

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,

impl IntoComponent for &ComponentRef<'_>

fn as_component_ref(&self) -> ComponentRef<'_>

Convert into a component directly.

fn into_component(self) -> Result<Component>

Convert into component.

impl IntoComponent for ComponentRef<'_>

fn as_component_ref(&self) -> ComponentRef<'_>

Convert into a component directly.

fn into_component(self) -> Result<Component>

Convert into component.

impl<'a> Ord for ComponentRef<'a>

fn cmp(&self, other: &ComponentRef<'a>) -> 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> PartialEq for ComponentRef<'a>

fn eq(&self, other: &ComponentRef<'a>) -> 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.

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> Serialize for ComponentRef<'a>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
