Struct rustc_resolve::ResolverArenas

pub struct ResolverArenas<'a> {
    modules: TypedArena<ModuleData<'a>>,
    local_modules: RefCell<Vec<&'a ModuleData<'a>>>,
    imports: TypedArena<Import<'a>>,
    name_resolutions: TypedArena<RefCell<NameResolution<'a>>>,
    ast_paths: TypedArena<Path>,
    dropless: DroplessArena,
}

Nothing really interesting here; it just provides memory for the rest of the crate.

Trait Implementations

impl<'a> Default for ResolverArenas<'a>

fn default() -> ResolverArenas<'a>

Returns the “default value” for a type.

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.
