Struct syntax::util::ThinVec

pub struct ThinVec<T>(_);

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

A vector type optimized for cases where this size is usually 0 (c.f. SmallVector). The Option<Box<..>> wrapping allows us to represent a zero sized vector with None, which uses only a single (null) pointer.
