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?

Encoding / decoding state for Lazy and LazySeq.

Variants

NoNode

🔬 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?

Outside of a metadata node.

NodeStart(usize)

🔬 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?

Inside a metadata node, and before any Lazy or LazySeq. The position is that of the node itself.

Previous(usize)

🔬 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?

Inside a metadata node, with a previous Lazy or LazySeq. The position is a conservative estimate of where that previous Lazy / LazySeq would end (see their comments).

Trait Implementations
