◆ BFN::PSA::MeterColorTypeTo8Bits

class BFN::PSA::MeterColorTypeTo8Bits

L-value of MeterColor_t is not deduced during an assignment E.g.:

struct metadata_t {
    PSA_MeterColor_t color_value;
}

gets converted to:

struct metadata_t {
    MeterColor_t color_value;
}

Usage is an assignment:

user_meta.color_value = meter0.execute(idx);

Output of meter is bit<8> which cannot be unified to MeterColor_t To overcome this issue, 'MeterColor_t' assignments occurring in Structs and Headers must be explicitly converted to an 8 bit value
