Struct WithRef

pub struct WithRef;

Expand description

Marker type for returning reference representing instance instead of allocating new string.

Trait Implementations§

impl Clone for WithRef

Performs copy-assignment from source. Read more

impl Debug for WithRef

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

Formats the value using the given formatter. Read more

Returns the “default value” for a type. Read more

impl<'a, T> ToStringWith<WithRef> for T
where T: 'a + AsRef<str> + ?Sized,

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> CloneToUninit for T
where T: Clone,

unsafe fn clone_to_uninit(&self, dest: *mut u8)

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

Performs copy-assignment from self to dest. Read more

impl<C, E> EntryToVal<C> for E
where C: Collection<Entry = E>,

type Val = <C as Collection>::Val

The type of values stored in the collection. This might be distinct from Entry in complex collections. For example, in a HashMap, while Entry might be a ( key, value ) tuple, Val might only be the value part.

fn entry_to_val(self) -> <E as EntryToVal<C>>::Val

Converts an entry into a value representation specific to the type of collection. This conversion is crucial for handling operations on entries, especially when they need to be treated or accessed as individual values, such as retrieving the value part from a key-value pair in a hash map.

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<T, U> Into<U> for T
where U: From<T>,

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

impl<T> ToOwned for T
where T: Clone,

type Owned = T

The resulting type after obtaining ownership.

fn to_owned(&self) -> T

Creates owned data from borrowed data, usually by cloning. Read more

fn clone_into(&self, target: &mut T)

Uses borrowed data to replace owned data, usually by cloning. Read more

impl<'a, T> ToStringWith<WithDebug> for T
where T: Debug + ?Sized,

fn to_string_with<'s>(&'s self) -> Cow<'s, str>

Converts the type to a string using Debug formatting.

impl<'a, T> ToStringWith<WithDebugMultiline> for T
where T: Debug + ?Sized,

fn to_string_with<'s>(&'s self) -> Cow<'s, str>

Converts the type to a string using Debug formatting.

impl<T, U> TryFrom<U> for T
where U: Into<T>,

type Error = Infallible

The type returned in the event of a conversion error.

fn try_from(value: U) -> Result<T, <T as TryFrom<U>>::Error>

Performs the conversion.

impl<T, U> TryInto<U> for T
where U: TryFrom<T>,

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.

impl<T> TypeName for T
where T: ?Sized,

fn type_name(&self) -> &'static str

Return name of type of variable.

impl<C, Val> ValToEntry<C> for Val
where C: CollectionValToEntry<Val>,

fn val_to_entry(self) -> <C as CollectionValToEntry<Val>>::Entry

Invokes the val_to_entry function of the CollectionValToEntry trait to convert the value to an entry.

type Entry = <C as CollectionValToEntry<Val>>::Entry

Represents the type of entry that corresponds to the value within the collection.

impl<T> CellRepr for T
where T: Copy + 'static,

impl<T> RowKey for T
