🔬 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?

The rib kind controls the translation of local definitions (Def::Local) to upvars (Def::Upvar).

Variants

NormalRibKind

🔬 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?

No translation needs to be applied.

ClosureRibKind(NodeId)

🔬 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?

We passed through a closure scope at the given node ID. Translate upvars as appropriate.

TraitOrImplItemRibKind

🔬 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?

We passed through an impl or trait and are now in one of its methods or associated types. Allow references to ty params that impl or trait binds. Disallow any other upvars (including other ty params that are upvars).

ItemRibKind

🔬 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?

We passed through an item scope. Disallow upvars.

ConstantItemRibKind

🔬 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?

We're in a constant item. Can't refer to dynamic stuff.

ModuleRibKind(&'a ModuleData<'a>)

🔬 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?

We passed through a module.

MacroDefinition(DefId)

🔬 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?

We passed through a macro_rules! statement

ForwardTyParamBanRibKind

🔬 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?

All bindings in this rib are type parameters that can't be used from the default of a type parameter because they're not declared before said type parameter. Also see the visit_generics override.
