Enum rune_core::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 id(self) -> Option<usize>

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

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

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,

Feeds a slice of this type into the given Hasher.

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 + PartialOrd,

Restrict a value to a certain interval.

impl<'a> PartialEq for ComponentRef<'a>

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> PartialOrd for ComponentRef<'a>

fn partial_cmp(&self, other: &ComponentRef<'a>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method 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.
