Struct rustc_hir_typeck::upvar::MigrationWarningReason
source · struct MigrationWarningReason {
auto_traits: Vec<&'static str>,
drop_order: bool,
}
Expand description
Reasons that we might issue a migration warning.
Fields§
§auto_traits: Vec<&'static str>
When we used to capture x
in its entirety, we implemented the auto-trait(s)
in this vec, but now we don’t.
drop_order: bool
When we used to capture x
in its entirety, we would execute some destructors
at a different time.

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.
