Struct rustc_session::config::Externs
source · pub struct Externs(BTreeMap<String, ExternEntry>);
Expand description
Use tree-based collections to cheaply get a deterministic Hash
implementation.
Do not switch BTreeMap
or BTreeSet
out for an unsorted container type! That
would break dependency tracking for command-line arguments.

Layout§
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.
