Struct quick_protobuf::reader::Reader

pub struct Reader { /* fields omitted */ }

A struct to read protobuf data

Contrary to BytesReader, this struct will own a buffer

Examples

// FooBar is a message generated from a proto file
// in parcicular it contains a `from_reader` function
use foo_bar::FooBar;
use quick_protobuf::Reader;

fn main() {
    // read an entire file into memory
    let mut reader = Reader::from_file("/myproject/resources/my_file.bin")
        .expect("Cannot read binary encoded file");

    // now using the generated module decoding is as easy as:
    let foobar = reader.read(FooBar::from_reader).expect("Cannot read FooBar");
    println!("Found {} foos and {} bars", foobar.foos.len(), foobar.bars.len());
}

Methods

impl Reader

fn from_reader<R: Read>(r: R, capacity: usize) -> Result<Reader>

Creates a new Reader

fn from_file<P: AsRef<Path>>(src: P) -> Result<Reader>

Creates a new Reader out of a file path

fn read<'a, M, F>(&'a mut self, read: F) -> Result<M> where F: FnMut(&mut BytesReader, &'a [u8]) -> Result<M>

Run a BytesReader dependent function
