Struct Regions

Source 
pub(crate) struct Regions {
    pub(crate) code_regions: Vec<CodeRegion>,
    pub(crate) branch_regions: Vec<BranchRegion>,
    pub(crate) mcdc_branch_regions: Vec<MCDCBranchRegion>,
    pub(crate) mcdc_decision_regions: Vec<MCDCDecisionRegion>,
}
Expand description

Holds tables of the various region types in one struct.

Don’t pass this struct across FFI; pass the individual region tables as pointer/length pairs instead.

Each field name has a _regions suffix for improved readability after exhaustive destructing, which ensures that all region types are handled.
