Struct syn::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<ExprGroup> for ExprGroup

Available on crate feature extra-traits only.

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

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

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.

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) -> TokenStreamwhere Self: Sized,

Convert self directly into a TokenStream object.

impl Eq for ExprGroup

Available on crate feature extra-traits only.
