Struct scale_info::interner::Symbol

pub struct Symbol<'a, T> { /* private fields */ }

A symbol from an interner.

Can be used to resolve to the associated instance.

Implementations

impl<T> Symbol<'_, T>

pub fn into_untracked(self) -> UntrackedSymbol<T>

Removes the lifetime tracking for this symbol.

Note

• This can be useful in situations where a data structure owns all symbols and interners and can verify accesses by itself.
• For further safety reasons an untracked symbol can no longer be used to resolve from an interner. It is still useful for serialization purposes.

Safety

Although removing lifetime constraints this operation can be considered to be safe since untracked symbols can no longer be used to resolve their associated instance from the interner.

Trait Implementations

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

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

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

Formats the value using the given formatter.

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

fn cmp(&self, other: &Symbol<'a, T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<'a, T: PartialEq> PartialEq<Symbol<'a, T>> for Symbol<'a, T>

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

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

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

Serialize this value into the given Serde serializer.
