Derive Macro pasture_derive::PointType

#[derive(PointType)]
{
    // Attributes available to this derive:
    #[pasture]
}

Custom derive macro that implements the PointType trait for the type that it is applied to.

Any that that wants to implement PointType using this derive macro must fulfill the following requirements:

• It must be at least one of #[repr(C)] and #[repr(packed)]
• All its members may only be Pasture primitive types
• Each member must contain an attribute #[pasture(X)], where X is either one of the builtin attributes explained below, or attribute = "name" for a custom attribute named name
• No two members may share the same attribute name

Builtin attributes

To associate a member of a custom PointType with one of the builtin point attributes in Pasture, use the #[pasture(X)] attribute, where X is one of:

• BUILTIN_POSITION_3D corresponding to the POSITION_3D attribute
• BUILTIN_INTENSITY corresponding to the INTENSITY attribute
• BUILTIN_RETURN_NUMBER corresponding to the RETURN_NUMBER attribute
• BUILTIN_NUMBER_OF_RETURNS corresponding to the NUMBER_OF_RETURNS attribute
• BUILTIN_CLASSIFICATION_FLAGS corresponding to the CLASSIFICATION_FLAGS attribute
• BUILTIN_SCANNER_CHANNEL corresponding to the SCANNER_CHANNEL attribute
• BUILTIN_SCAN_DIRECTION_FLAG corresponding to the SCAN_DIRECTION_FLAG attribute
• BUILTIN_EDGE_OF_FLIGHT_LINE corresponding to the EDGE_OF_FLIGHT_LINE attribute
• BUILTIN_CLASSIFICATION corresponding to the CLASSIFICATION attribute
• BUILTIN_SCAN_ANGLE_RANK corresponding to the SCAN_ANGLE_RANK attribute
• BUILTIN_SCAN_ANGLE corresponding to the SCAN_ANGLE attribute
• BUILTIN_USER_DATA corresponding to the USER_DATA attribute
• BUILTIN_POINT_SOURCE_ID corresponding to the POINT_SOURCE_ID attribute
• BUILTIN_COLOR_RGB corresponding to the COLOR_RGB attribute
• BUILTIN_GPS_TIME corresponding to the GPS_TIME attribute
• BUILTIN_NIR corresponding to the NIR attribute
• BUILTIN_WAVE_PACKET_DESCRIPTOR_INDEX corresponding to the WAVE_PACKET_DESCRIPTOR_INDEX attribute
• BUILTIN_WAVEFORM_DATA_OFFSET corresponding to the WAVEFORM_DATA_OFFSET attribute
• BUILTIN_WAVEFORM_PACKET_SIZE corresponding to the WAVEFORM_PACKET_SIZE attribute
• BUILTIN_RETURN_POINT_WAVEFORM_LOCATION corresponding to the RETURN_POINT_WAVEFORM_LOCATION attribute
• BUILTIN_WAVEFORM_PARAMETERS corresponding to the WAVEFORM_PARAMETERS attribute

Custom attributes

To associate a member of a custom PointType with a point attribute with custom name, use the #[pasture(attribute = "name")] attribute
