Cargo Features

coin_cbc = { version = "0.1.8", default-features = false, features = ["singlethread-cbc", "cbc-310"] }
default = singlethread-cbc

The singlethread-cbc feature is set by default whenever coin_cbc is added without default-features = false somewhere in the dependency tree.

singlethread-cbc default = lazy_static

The singlethread-cbc feature MUST be activated if this crate is going to be used with a cbc dynamic library that has not been explicitly compiled with -DCBC_THRED_SAFE. For more information, see


The cbc-310 feature activates features only available in Coin-OR Cbc version >= 3.10
Notably, this gives useful methods for interpreting linear problem solutions.
Using the methods protected by this flag will raise a runtime error when the target system has a version of libcbc older than 3.10.

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
