Expand description

Write a struct.

See BodyBuf::store_struct.

Implementations§

Source §

impl<'a, T> StoreStruct<'a, T>

Source

pub fn store( self, value: <T::First as Marker>::Return<'_>, ) -> StoreStruct<'a, T::Remaining>
where T: Fields, T::First: Marker, for<'b> <T::First as Marker>::Return<'b>: Storable,

Store a value and return the builder for the next value to store.

§Examples

use tokio_dbus::{BodyBuf, Endianness};
use tokio_dbus::ty;

let mut buf = BodyBuf::with_endianness(Endianness::LITTLE);

buf.store_struct::<(u16, u32)>()?
    .store(10u16)
    .store(10u32)
    .finish();

assert_eq!(buf.signature(), b"(qu)");
assert_eq!(buf.get(), &[10, 0, 0, 0, 10, 0, 0, 0]);

Examples using unsized types:

use tokio_dbus::{BodyBuf, Endianness};
use tokio_dbus::ty;

let mut buf = BodyBuf::with_endianness(Endianness::LITTLE);

buf.store_struct::<(ty::Str,)>()?
    .store("Hello World")
    .finish();

assert_eq!(buf.signature(), b"(s)");
assert_eq!(buf.get(), &[11, 0, 0, 0, 72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100, 0]);

Source

pub fn fields(self, arguments: T)
where T: Arguments,

Store a value and return the builder for the next value to store.

§Examples

use tokio_dbus::{BodyBuf, Endianness};
use tokio_dbus::ty;

let mut buf = BodyBuf::with_endianness(Endianness::LITTLE);

buf.store_struct::<(u8, u32)>()?.fields((42u8, 42u32));

assert_eq!(buf.signature(), b"(yu)");
assert_eq!(buf.get(), &[42, 0, 0, 0, 42, 0, 0, 0]);

Source

pub fn store_array<W, U>(self, writer: W) -> StoreStruct<'a, T::Remaining>
where W: FnOnce(&mut StoreArray<'_, U>), T: Fields<First = Array>, U: Aligned,

Store a value and return the builder for the next value to store.

§Examples

use tokio_dbus::{BodyBuf, Endianness};
use tokio_dbus::ty;

let mut buf = BodyBuf::with_endianness(Endianness::LITTLE);

buf.store_struct::<(ty::Array<u32>,)>()?
    .store_array(|w| {
        w.store(1);
        w.store(2);
        w.store(3);
        w.store(4);
    })
    .finish();

assert_eq!(buf.signature(), b"(au)");
assert_eq!(buf.get(), &[16, 0, 0, 0, 1, 0, 0, 0, 2, 0, 0, 0, 3, 0, 0, 0, 4, 0, 0, 0]);
