Implementations

impl VarDeclOrExpr

pub const fn is_var_decl(&self) -> bool

Returns true if self is of variant VarDecl.

pub fn as_var_decl(&self) -> Option<&Box<VarDecl>>

Returns Some if self is a reference of variant VarDecl, and None otherwise.

pub fn as_mut_var_decl(&mut self) -> Option<&mut Box<VarDecl>>

Returns Some if self is a mutable reference of variant VarDecl, and None otherwise.

pub fn expect_var_decl(self) -> Box<VarDecl>

where VarDeclOrExpr: Debug,

Unwraps the value, yielding the content of VarDecl.

Panics

Panics if the value is not VarDecl, with a panic message including the content of self.

pub fn var_decl(self) -> Option<Box<VarDecl>>

Returns Some if self is of variant VarDecl, and None otherwise.

pub const fn is_expr(&self) -> bool

Returns true if self is of variant Expr.

pub fn as_expr(&self) -> Option<&Box<Expr>>

Returns Some if self is a reference of variant Expr, and None otherwise.

pub fn as_mut_expr(&mut self) -> Option<&mut Box<Expr>>

Returns Some if self is a mutable reference of variant Expr, and None otherwise.

pub fn expect_expr(self) -> Box<Expr>

where VarDeclOrExpr: Debug,

Unwraps the value, yielding the content of Expr.

Panics

Panics if the value is not Expr, with a panic message including the content of self.

pub fn expr(self) -> Option<Box<Expr>>

Returns Some if self is of variant Expr, and None otherwise.

Trait Implementations

impl Clone for VarDeclOrExpr

fn clone(&self) -> VarDeclOrExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VarDeclOrExpr

Calls Fold::fold_var_decl_or_expr with self.

fn fold_children_with(self, visitor: &mut V) -> VarDeclOrExpr

Visit children nodes of self`` with visitor`.

impl<'ast> From<&'ast VarDeclOrExpr> for NodeRef<'ast>

fn from(node: &'ast VarDeclOrExpr) -> NodeRef<'ast>

Converts to this type from the input type.

impl Hash for VarDeclOrExpr

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

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.
