Struct ExprEmpty 

#[non_exhaustive]
pub struct ExprEmpty {
    pub attributes: Vec<Attribute>,
    pub open: OpenEmpty,
    pub expr: Box<Expr>,
    pub close: CloseEmpty,
}

A prioritized expression group without delimiters <expr>.

These groups are only produced during internal desugaring. Most notably through the use of template literals.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

attributes: Vec<Attribute>

Attributes associated with expression.

open: OpenEmpty

The open parenthesis.

expr: Box<Expr>

The grouped expression.

close: CloseEmpty

The close parenthesis.
