Function fail::setup

pub fn setup()

Set up the fail point system.

Configures all fail points specified in the FAILPOINTS environment variable. It does not otherwise change any existing fail point configuration

The format of FAILPOINTS is failpoint=actions;..., where failpoint is the name of the fail point. For more information about fail point actions see the cfg function and the fail_point macro.

FAILPOINTS may configure fail points that are not actually defined. In this case the configuration has no effect.

This function should generally be called prior to running a test with fail points, and afterward paired with teardown.

Panics

Panics if an action is not formatted correctly.
