Struct rustc::infer::region_inference::SameRegions

pub struct SameRegions {
    pub scope_id: NodeId,
    pub regions: Vec<BoundRegion>,
}

Unstable (rustc_private)

SameRegions is used to group regions that we think are the same and would like to indicate so to the user. For example, the following function struct Foo { bar: i32 } fn foo2<'a, 'b>(x: &'a Foo) -> &'b i32 { &x.bar } would report an error because we expect 'a and 'b to match, and so we group 'a and 'b together inside a SameRegions struct
