Enum rustc_session::config::Lto

pub enum Lto {
    No,
    Thin,
    ThinLocal,
    Fat,
}

This is what the LtoCli values get mapped to after resolving defaults and and taking other command line options into account.

Note that linker plugin-based LTO is a different mechanism entirely.

Variants

No

Don’t do any LTO whatsoever.

Thin

Do a full-crate-graph (inter-crate) LTO with ThinLTO.

ThinLocal

Do a local ThinLTO (intra-crate, over the CodeGen Units of the local crate only). This is only relevant if multiple CGUs are used.

Fat

Do a full-crate-graph (inter-crate) LTO with “fat” LTO.

Trait Implementations

impl Clone for Lto

fn clone(&self) -> Lto

Returns a copy of the value.

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

Performs copy-assignment from source.

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.
