Struct rustc_session::config::Externs[−][src]

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.
