Struct predicates::path::BinaryFilePredicate

pub struct BinaryFilePredicate { /* fields omitted */ }

Predicate that compares file matches

Methods

impl BinaryFilePredicate

pub fn utf8(self) -> Option<StrFilePredicate>

Creates a new Predicate that ensures complete equality

Examples

use std::path::Path;
use predicates::prelude::*;

let predicate_file = predicate::path::eq_file(Path::new("Cargo.toml")).utf8().unwrap();
assert_eq!(true, predicate_file.eval(Path::new("Cargo.toml")));
assert_eq!(false, predicate_file.eval(Path::new("Cargo.lock")));
assert_eq!(false, predicate_file.eval(Path::new("src")));

assert_eq!(false, predicate_file.eval("Not a real Cargo.toml file content"));

Trait Implementations

impl Eq for BinaryFilePredicate

impl PartialEq<BinaryFilePredicate> for BinaryFilePredicate

fn eq(&self, other: &BinaryFilePredicate) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &BinaryFilePredicate) -> bool

This method tests for !=.

impl Clone for BinaryFilePredicate

fn clone(&self) -> BinaryFilePredicate

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Display for BinaryFilePredicate

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Debug for BinaryFilePredicate

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Predicate<Path> for BinaryFilePredicate

fn eval(&self, path: &Path) -> bool

Execute this Predicate against variable, returning the resulting boolean.

fn find_case<'a>(&'a self, expected: bool, variable: &Path) -> Option<Case<'a>>

Find a case that proves this predicate as expected when run against variable.

impl Predicate<[u8]> for BinaryFilePredicate

fn eval(&self, actual: &[u8]) -> bool

Execute this Predicate against variable, returning the resulting boolean.

fn find_case<'a>(&'a self, expected: bool, variable: &[u8]) -> Option<Case<'a>>

Find a case that proves this predicate as expected when run against variable.

impl PredicateReflection for BinaryFilePredicate

fn parameters<'a>(&'a self) -> Box<dyn Iterator<Item = Parameter<'a>> + 'a>

Parameters of the current Predicate.

fn children(&'a self) -> Box<dyn Iterator<Item = Child<'a>> + 'a>

Nested Predicates of the current Predicate.
