Enum rustc_mir::borrow_check::nll::region_infer::Cause [−][src]
pub(crate) enum Cause { LiveVar(Local, Location), DropVar(Local, Location), LiveOther(Location), UniversalRegion(RegionVid), }
🔬 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?
NB: The variants in Cause
are intentionally ordered. Lower
values are preferred when it comes to error messages. Do not
reorder willy nilly.
Variants
LiveVar(Local, Location)
🔬 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?
point inserted because Local was live at the given Location
DropVar(Local, Location)
🔬 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?
point inserted because Local was dropped at the given Location
LiveOther(Location)
🔬 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?
point inserted because the type was live at the given Location, but not as part of some local variable
UniversalRegion(RegionVid)
🔬 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?
part of the initial set of values for a universally quantified region
