Struct GTFSRealtimeReader 

pub struct GTFSRealtimeReader {
    pub header: GTFSRealtimeHeader,
    pub entities: Vec<GTFSRealtimeEntity>,
}

GTFS Realtime message.

Description

The input is a Uint8Array that has encoded protobuffer messages. See https://open-s2.github.io/pbf/classes/PbfReader.html.

The contents of a feed message. A feed is a continuous stream of feed messages. Each message in the stream is obtained as a response to an appropriate HTTP GET request. A realtime feed is always defined with relation to an existing GTFS feed. All the entity ids are resolved with respect to the GTFS feed. Note that “required” and “optional” as stated in this file refer to Protocol Buffer cardinality, not semantic cardinality. See reference.md at https://github.com/google/transit/tree/master/gtfs-realtime for field semantic cardinality.

Usage

The methods you have access to:

• GTFSRealtimeReader::new: Create a new GTFSRealtimeReader

use gistools::readers::GTFSRealtimeReader;
use std::path::PathBuf;
  
let mut path = PathBuf::from(env!("CARGO_MANIFEST_DIR"));
path.push("tests/readers/gtfs/fixtures/vehicle_position.pb");

let data = std::fs::read(path).unwrap();
let reader = GTFSRealtimeReader::new(data, None);

let entities = &reader.entities;
assert_eq!(entities.len(), 1);

Implementations

impl GTFSRealtimeReader

pub fn new(data: Vec<u8>, end: Option<usize>) -> Self

Create a new GTFSRealtimeReader

Trait Implementations

impl Clone for GTFSRealtimeReader

fn clone(&self) -> GTFSRealtimeReader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GTFSRealtimeReader

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

Formats the value using the given formatter.

impl Default for GTFSRealtimeReader

fn default() -> GTFSRealtimeReader

Returns the “default value” for a type.

impl PartialEq for GTFSRealtimeReader

fn eq(&self, other: &GTFSRealtimeReader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ProtoRead for GTFSRealtimeReader

Read in the contents of the GTFSRealtimeReader

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.
