Struct tryrun::Output

pub struct Output<StdOut, StdErr> {
    pub stdout: Option<StdOut>,
    pub stderr: Option<StdErr>,
}

Path to files that store expected Command stdout and stderr.

None means expecting stdout or stderr to be empty. Note that providing an empty file does not work and will resulting an “output is empty” assertion failure.

Fields

stdout: Option<StdOut>

Path to the stdout file.

stderr: Option<StdErr>

Path to the stderr file.

Implementations

impl<StdOut, StdErr> Output<StdOut, StdErr>

#[must_use]

pub const fn empty() -> Self

Expects empty output.

Example

const EMPTY: OutputStr = OutputStr::empty();
assert!(EMPTY.stdout.is_none());
assert!(EMPTY.stderr.is_none());

#[must_use]

pub const fn stdout(stdout: StdOut) -> Self

Expects stdout to match the specified file and empty stderr.

Example

const STDOUT_ONLY: OutputStr = OutputStr::stdout("foo/bar.stdout");
assert_eq!(STDOUT_ONLY.stdout.unwrap(), "foo/bar.stdout");
assert!(STDOUT_ONLY.stderr.is_none());

#[must_use]

pub const fn stderr(stderr: StdErr) -> Self

Expects stderr to match the specified file and empty stdout.

Example

const STDERR_ONLY: OutputStr = OutputStr::stderr("foo/bar.stderr");
assert!(STDERR_ONLY.stdout.is_none());
assert_eq!(STDERR_ONLY.stderr.unwrap(), "foo/bar.stderr");
