Struct PrimitiveBlock 

pub struct PrimitiveBlock {
    pub primitive_groups: Vec<PrimitiveGroup>,
    pub granularity: i32,
    pub lat_offset: i64,
    pub lon_offset: i64,
    pub date_granularity: i32,
    /* private fields */
}

NOTE: currently relations are stored, but we don’t wait for the Block to store all relations before we start testing primtiveHandle against the data. This is a problem because relations reference eachother at times, and we need to be able to resolve those references before we can run relationHandle against the data. This isn’t an important issue since in practice, all relations that reference eachother often produce garbage or unusable data. But it would be nice to fix this. Morbidly enough, the “BEST” solution is to treat relations like we do nodes and ways since relations could possibly reference eachother outside their own block. From a practical standpoint, I can’t see this being worth the effort or memory/time cost.

Fields

primitive_groups: Vec<PrimitiveGroup>

Primitive groups are smaller collections of the nodes, ways and relations

granularity: i32

Granularity, units of nanodegrees, used to store coordinates in this block.

lat_offset: i64

Offset value between the output coordinates and the granularity grid in units of nanodegrees.

lon_offset: i64

Offset value between the output coordinates and the granularity grid in units of nanodegrees.

date_granularity: i32

Granularity of dates, normally represented in units of milliseconds since the 1970 epoch.

Implementations

impl PrimitiveBlock

pub fn get_string(&self, index: usize) -> &str

Get a string from the string table

pub fn tags(&self, keys: &[u32], values: &[u32]) -> Properties

Get a record of strings from the string table

Trait Implementations

impl Debug for PrimitiveBlock

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PrimitiveBlock

fn default() -> Self

Returns the “default value” for a type.

impl ProtoRead for PrimitiveBlock

Read in the contents of the primitive block

fn read(&mut self, tag: u64, pb: &mut Protobuf)

The read method is used to read a field from a protobuf message. The tag parameter is used to determine which field to read into the struct. The pbf parameter is used to read the data in the appropriate format.
