Struct ExprGroup

pub struct ExprGroup {
    pub attrs: Vec<Attribute>,
    pub group_token: Group,
    pub expr: Box<Expr>,
}

Available on crate feature full only.

An expression contained within invisible delimiters.

This variant is important for faithfully representing the precedence of expressions and is related to None-delimited spans in a TokenStream.

Fields

attrs: Vec<Attribute>

group_token: Group

expr: Box<Expr>

Trait Implementations

impl Clone for ExprGroup

Available on crate feature clone-impls only.

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExprGroup

Available on crate feature extra-traits only.

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

Formats the value using the given formatter.

impl From<ExprGroup> for Expr

fn from(e: ExprGroup) -> Expr

Converts to this type from the input type.

impl Hash for ExprGroup

Available on crate feature extra-traits only.

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

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ExprGroup

Available on crate feature extra-traits only.

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToTokens for ExprGroup

Available on crate feature printing only.

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

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.

impl Eq for ExprGroup

Available on crate feature extra-traits only.

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.
