Enum Mode 

#[non_exhaustive]
pub enum Mode {
    Lines,
    Trim,
    TrimAll,
}

Normalization strategy shared by all of the assertion macros.

It is exposed so the exact same normalization the macros use can be reused outside of assertions – for example to pre-process snapshots, build whitespace-insensitive hash/sort keys, or write your own comparison via normalize.

This enum is #[non_exhaustive]: additional modes may be added in future releases without a breaking change.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Lines

Compare line by line, treating \n and \r\n as equivalent. A single trailing newline is ignored (a consequence of str::lines).

Trim

Like Mode::Lines, but additionally trims each line and drops empty lines.

TrimAll

Removes all whitespace anywhere in the string (spaces, tabs, and line breaks). Useful for comparing minified and pretty-printed formats.
