[−][src]Trait predicates::prelude::PredicateStrExt

pub trait PredicateStrExt where
    Self: Predicate<str>,
    Self: Sized, {
    fn trim(self) -> TrimPredicate<Self> { ... }

    fn from_utf8(self) -> Utf8Predicate<Self> { ... }

    fn normalize(self) -> NormalizedPredicate<Self> { ... }
}

Predicate extension adapting a str Predicate.

Provided methods

fn trim(self) -> TrimPredicate<Self>

Returns a TrimPredicate that ensures the data passed to Self is trimmed.

Examples

use predicates::prelude::*;

let predicate_fn = predicate::str::is_empty().trim();
assert_eq!(true, predicate_fn.eval("    "));
assert_eq!(false, predicate_fn.eval("    Hello    "));

fn from_utf8(self) -> Utf8Predicate<Self>

Returns a Utf8Predicate that adapts Self to a [u8] Predicate.

Examples

use predicates::prelude::*;
use std::ffi::OsStr;

let predicate_fn = predicate::str::is_empty().not().from_utf8();
assert_eq!(true, predicate_fn.eval(OsStr::new("Hello")));
assert_eq!(false, predicate_fn.eval(OsStr::new("")));
let variable: &[u8] = b"";
assert_eq!(false, predicate_fn.eval(variable));

fn normalize(self) -> NormalizedPredicate<Self>

Returns a NormalizedPredicate that ensures the newlines within the data passed to Self is normalised.

Examples

use predicates::prelude::*;

let predicate_fn = predicate::eq("Hello World!\n").normalize();
assert_eq!(true, predicate_fn.eval("Hello World!\n"));
assert_eq!(true, predicate_fn.eval("Hello World!\r"));
assert_eq!(true, predicate_fn.eval("Hello World!\r\n"));
assert_eq!(false, predicate_fn.eval("Goodbye"));
