Struct novatel_oem6_api::mock::ReadStruct

pub struct ReadStruct { /* fields omitted */ }

Structure containing the output data or result to return when the MockStream's read function is called

Methods

impl ReadStruct

pub fn set_result(&mut self, result: Result<Vec<u8>, UartError>)

Set the result to be returned for any read() calls

Note: This will be ignored if set_output is also used

Arguments

• result - The UartResult to return in future read() calls

Examples

use rust_uart::*;
use rust_uart::mock::*;
use std::time::Duration;

fn test_read_error_io() {
    let mut mock = MockStream::default();

    mock.read
        .set_result(Err(UartError::GenericError.into()));

    let connection = Connection {
        stream: Box::new(mock),
    };

    assert_eq!(
        connection.read(5, Duration::new(0, 0)).unwrap_err(),
        UartError::GenericError
    );
}

pub fn set_output(&mut self, output: Vec<u8>)

Set the output data

Arguments

• output - The output buffer which future read() calls should retrieve data from

Examples

use rust_uart::*;
use rust_uart::mock::*;
use std::time::Duration;

fn test_read_good_multi() {
    let mut mock = MockStream::default();

    let expected = vec![0, 1, 2, 3, 4, 5];

    mock.read.set_output(expected.clone());

    let connection = Connection {
        stream: Box::new(mock),
    };

    assert_eq!(
        connection.read(3, Duration::new(0, 0)).unwrap(),
        vec![0, 1, 2]
    );
    assert_eq!(
        connection.read(3, Duration::new(0, 0)).unwrap(),
        vec![3, 4, 5]
    );
}
