Struct predicates::str::DifferencePredicate

pub struct DifferencePredicate { /* fields omitted */ }

Predicate that diffs two strings.

This is created by the predicate::str::similar.

Methods

impl DifferencePredicate

pub fn split<S>(self, split: S) -> Self where
    S: Into<Cow<'static, str>>, 

The split used when identifying changes.

Common splits include:

• "" for char-level.
• " " for word-level.
• "\n" for line-level.

Default: "\n"

Examples

use predicates::prelude::*;

let predicate_fn = predicate::str::similar("Hello World").split(" ");
assert_eq!(true, predicate_fn.eval("Hello World"));

pub fn distance(self, distance: i32) -> Self

The maximum allowed edit distance.

Default: 0

Examples

use predicates::prelude::*;

let predicate_fn = predicate::str::similar("Hello World!").split("").distance(1);
assert_eq!(true, predicate_fn.eval("Hello World!"));
assert_eq!(true, predicate_fn.eval("Hello World"));
assert_eq!(false, predicate_fn.eval("Hello World?"));
