Trait Implementations

impl<T, S> Clone for Sp<T, S>

where T: Clone, S: Clone,

fn clone(&self) -> Sp<T, S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T, S> Debug for Sp<T, S>

where T: Debug, S: Debug,

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

Formats the value using the given formatter.

impl<'de, T, S> Deserialize<'de> for Sp<T, S>

where T: Deserialize<'de>, S: Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D, ) -> Result<Sp<T, S>, <__D as Deserializer<'de>>::Error>

Formats the value using the given formatter.

impl<T> Error for Sp<T>

where T: Error,

fn source(&self) -> Option<&(dyn Error + 'static)>

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl<T> From<Sp<T>> for Sp<T, Span>

fn from(value: Sp<T>) -> Sp<T, Span>

Converts to this type from the input type.

impl<T, S> From<SpRep<T, S>> for Sp<T, S>

fn from(_: SpRep<T, S>) -> Sp<T, S>

Converts to this type from the input type.

impl<T, S> Hash for Sp<T, S>

where T: Hash, S: Hash,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl<T, S> Ord for Sp<T, S>

where T: Ord, S: Ord,

fn cmp(&self, other: &Sp<T, 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.

where T: PartialOrd, S: PartialOrd,

fn partial_cmp(&self, other: &Sp<T, S>) -> Option<Ordering>

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