Trait Implementations

impl ExtractExpr for DefaultExpr

type InnerExpr = Expr

Defines superset of Expr used by given struct.

fn extract_expr(&self) -> &Expr

Extracts Expr from given value.

fn extract_inner_expr(&self) -> &Self::InnerExpr

Extracts InnerExpr. If InnerExpr is Expr, acts as extract_expr.

impl ReplaceExpr for DefaultExpr

fn replace_expr(&self, expr: Expr) -> Option<Self>

Replaces current expr by given Expr if it's possible, returning Some(new Self) with given Expr, otherwise returns None.

fn is_replaceable(&self) -> bool

Can expr be replaced or not.

impl Clone for DefaultExpr

fn clone(&self) -> DefaultExpr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for DefaultExpr

impl PartialEq<DefaultExpr> for DefaultExpr

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

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

fn ne(&self, other: &DefaultExpr) -> bool

This method tests for !=.

impl Debug for DefaultExpr

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

Formats the value using the given formatter.

impl ToTokens for DefaultExpr

fn to_tokens(&self, output: &mut TokenStream)

Write self to the given TokenStream.

fn into_token_stream(self) -> TokenStream

Convert self directly into a TokenStream object.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.
