Trait tryrun::Normalizer

pub trait Normalizer {
    fn normalize_stdout<'a>(&mut self, stdout: &'a mut Vec<u8>) -> &'a [u8] { ... }
    fn normalize_stderr<'a>(&mut self, stderr: &'a mut Vec<u8>) -> &'a [u8] { ... }
}

Normalizer to normalize stdout and stderr.

Provided methods

fn normalize_stdout<'a>(&mut self, stdout: &'a mut Vec<u8>) -> &'a [u8]

Normalizes stdout. The returned value of this function will be used to compare stdout.

The default implementation does not do any normalization:

struct DefaultNormalizer;
impl Normalizer for DefaultNormalizer {}
assert_eq!(DefaultNormalizer.normalize_stdout(&mut b"foo".to_vec()), b"foo");

fn normalize_stderr<'a>(&mut self, stderr: &'a mut Vec<u8>) -> &'a [u8]

Normalizes stderr. The returned value of this function will be used to compare stderr.

The default implementation does not do any normalization:

struct DefaultNormalizer;
impl Normalizer for DefaultNormalizer {}
assert_eq!(DefaultNormalizer.normalize_stderr(&mut b"ar".to_vec()), b"ar");
