Struct CallingContext 

Source 
pub struct CallingContext {
    pub maps: Vec<MapSchema>,
    pub helpers: HashMap<u32, &'static HelperDefinition>,
    pub args: Vec<Type>,
    pub packet_type: Option<Type>,
}

Fields§

§maps: Vec<MapSchema>

List of map schemas of the associated map. The maps can be accessed using LDDW instruction with src_reg=BPF_PSEUDO_MAP_IDX.

§helpers: HashMap<u32, &'static HelperDefinition>

The registered external functions.

§args: Vec<Type>

The args of the program.

§packet_type: Option<Type>

Packet type. Normally it should be either None or args[0].
