pub enum VecArgs<'a> {
    Repeat(&'a Expr<'a>, &'a Expr<'a>),
    Vec(&'a [Expr<'a>]),
}

Represent the pre-expansion arguments of a vec! invocation.

1: &'a Expr<'a>

vec![elem; len]

Vec(&'a [Expr<'a>])

Implementations

impl<'a> VecArgs<'a>

pub fn hir(cx: &LateContext<'_>, expr: &'a Expr<'_>) -> Option<VecArgs<'a>>

Returns the arguments of the vec! macro if this expression was expanded from vec!.

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.
