Struct LookupRef 

pub struct LookupRef {
    pub found: bool,
    pub data_offset: u32,
    pub prefix_len: u8,
    pub result_type: u8,
}

Zero-allocation lookup result for C API. Stores offsets into mmap’d data instead of owned values.

Fields

found: bool

Whether a match was found

data_offset: u32

Offset to data in the MMDB data section (0 if not found or no data)

prefix_len: u8

Network prefix length (for IP results, 0 for patterns)

result_type: u8

Result type: 0=not found, 1=ip, 2=pattern

Create a not-found result

pub const fn ip(data_offset: u32, prefix_len: u8) -> Self
