Trait Implementations§

source §

impl Clone for AstFragmentKind

source §

fn clone(&self) -> AstFragmentKind

Returns a copy of the value. Read more

1.0.0 · source§

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

Performs copy-assignment from source. Read more

source §

impl PartialEq<AstFragmentKind> for AstFragmentKind

source §

fn eq(&self, other: &AstFragmentKind) -> bool

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

1.0.0 · source§

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. Read more

Blanket Implementations§

source §

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

source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

source §

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

const: unstable · source§

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

source §

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

const: unstable · source§

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

Mutably borrows from an owned value. Read more

source §

impl<T> From<T> for T

const: unstable · source§

fn from(t: T) -> T

Returns the argument unchanged.

source §

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

const: unstable · source§

fn into(self) -> U

Calls U::from(self).

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

source §

impl<T> ToOwned for Twhere
T: Clone,

§

type Owned = T

The resulting type after obtaining ownership.

source §

fn to_owned(&self) -> T

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

source §

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

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

source §

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

§

type Error = Infallible

The type returned in the event of a conversion error.

const: unstable · source§

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

Performs the conversion.

source §

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

§

type Error = >::Error

The type returned in the event of a conversion error.

const: unstable · source§

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

Performs the conversion.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
