Struct Check

pub struct Check<T> { /* private fields */ }

This is a wrapper around a copyable message to check constness

Implementations

impl<T> Check<T>

pub fn new(value: T) -> Self

Create a new check for a Message

Example

use rdp::model::data::{Check, U16, Message};
use std::io::Cursor;
let mut s = Cursor::new(vec![4, 0]);
let mut x = Check::new(U16::LE(4));
assert!(!x.read(&mut s).is_err());

let mut s2 = Cursor::new(vec![5, 0]);
assert!(x.read(&mut s2).is_err());

Trait Implementations

impl<T: Message + Clone + PartialEq> Message for Check<T>

fn write(&self, writer: &mut dyn Write) -> RdpResult<()>

Check values doesn’t happen during write steps

fn read(&mut self, reader: &mut dyn Read) -> RdpResult<()>

Check value will be made during reading steps

Example

use rdp::model::data::{Check, U16, Message};
use std::io::Cursor;
let mut s = Cursor::new(vec![4, 0]);
let mut x = Check::new(U16::LE(4));
assert!(!x.read(&mut s).is_err());

let mut s2 = Cursor::new(vec![5, 0]);
assert!(x.read(&mut s2).is_err());

fn length(&self) -> u64

This is the length of the inner value

fn visit(&self) -> DataType<'_>

Same as visit of the inner value

Example

    let mut s = Cursor::new(vec![8, 0, 0, 0, 3]);
    let mut x = trame![
        Check::new(U32::LE(8)),
        0 as u8
    ];
    x.read(&mut s);
    assert_eq!(cast!(DataType::U32, x[0]).unwrap(), 8)

fn options(&self) -> MessageOption

No option
