Function phytrace_builder_set_location 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn phytrace_builder_set_location(
    builder: *mut PhyTraceBuilderHandle,
    latitude: f64,
    longitude: f64,
    altitude_m: f64,
    heading_deg: f64,
    x_m: f64,
    y_m: f64,
    z_m: f64,
    yaw_deg: f64,
    frame_id: *const c_char,
    map_id: *const c_char,
    floor: i32,
) -> i32

Set the location domain on the builder.

All floating-point parameters use f64::NAN to indicate “not set”. String parameters use null to indicate “not set”.

Parameters

• latitude — GPS latitude in decimal degrees (-90 to 90), or NAN
• longitude — GPS longitude in decimal degrees (-180 to 180), or NAN
• altitude_m — Altitude in meters above sea level, or NAN
• heading_deg — Heading in degrees (0-360), or NAN
• x_m — Local X coordinate in meters, or NAN
• y_m — Local Y coordinate in meters, or NAN
• z_m — Local Z coordinate in meters, or NAN
• yaw_deg — Local yaw angle in degrees, or NAN
• frame_id — Reference frame ID (e.g., “map”, “odom”), or null
• map_id — Map identifier, or null
• floor — Floor number; i32::MIN means “not set”
