Struct rustc_ap_rustc_session::config::Externs

pub struct Externs(_);

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.

Implementations

impl Externs

pub fn new(data: BTreeMap<String, ExternEntry>) -> Externs

Used for testing.

pub fn get(&self, key: &str) -> Option<&ExternEntry>

pub fn iter(&self) -> BTreeMapIter<'_, String, ExternEntry>

pub fn len(&self) -> usize

Trait Implementations

impl Clone for Externs

fn clone(&self) -> Externs

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
