NoExt

Enum NoExt 

Source
pub enum NoExt {}
Expand description

The stock parser extension type.

This type is uninhabited, so Other(NoExt) variants are statically dead and do not increase stock AST node sizes.

Blanket Implementations§

Source§

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

Source§

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more
Source§

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

Source§

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more
Source§

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

Source§

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

Mutably borrows from an owned value. Read more
Source§

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

Source§

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
Source§

impl<T> DeserializeOwned for T
where T: for<'de> Deserialize<'de>,

Source§

impl<T> DynAstExt for T
where T: Extension + Render + 'static,

Source§

fn as_any(&self) -> &(dyn Any + 'static)

Erase to &dyn Any for downcasting a node back to its concrete type.
Source§

fn dyn_clone(&self) -> Box<dyn DynAstExt>

Clone into a fresh box — the object-safe stand-in for Clone (whose Self-returning signature cannot go through a vtable).
Source§

fn dyn_eq(&self, other: &dyn DynAstExt) -> bool

Structural equality against another erased node — the object-safe stand-in for PartialEq (whose &Self argument cannot go through a vtable). Equal iff other holds the same concrete type and that type deems the values equal; differently-typed nodes are never equal.
Source§

fn dyn_hash(&self, state: &mut dyn Hasher)

Feed this node’s hash into an erased hasher — the object-safe stand-in for Hash::hash (whose generic H: Hasher cannot go through a vtable).
Source§

impl<T> Extension for T
where T: Clone + Debug + Eq + Hash + Spanned,

Source§

impl<T> From<T> for T

Source§

fn from(t: T) -> T

Returns the argument unchanged.

Source§

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

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> RenderExt for T
where T: Render,

Source§

fn displayed<'a>(&'a self, ctx: &'a RenderCtx<'a>) -> Displayed<'a, T>

Pair this node with an explicit canonical RenderCtx so format!, to_string, and {} render it. This is the canonical path: the ctx’s resolver and source must match the node’s parse.
Source§

fn debug_sql<'a>(&'a self, resolver: &'a dyn Resolver) -> DebugSql<'a, Self>
where Self: Sized,

Render this node for debugging against an explicitly-supplied resolver (the debug-SQL mitigation), returning a Display adapter. Read more
Source§

type Owned = T

The resulting type after obtaining ownership.
Source§

fn to_owned(&self) -> T
