Type Alias Value 

pub type Value<'tcx> = CrateDepKind;

Aliased Type

pub enum Value<'tcx> {
    MacrosOnly,
    Conditional,
    Unconditional,
}

Variants

MacrosOnly

A dependency that is only used for its macros.

Conditional

A dependency that is injected into the crate graph but which only sometimes needs to actually be linked in, e.g., the injected panic runtime.

Unconditional

A dependency that is required by an rlib version of this crate. Ordinary extern crates as well as most injected dependencies result in Unconditional dependencies.

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.
