Struct Closure 

pub struct Closure<F> { /* private fields */ }

Closure based predicate.

Create

This type can be created through From and Into traits for any type, however, it only implements Filter when F: Fn(&Path) -> bool

You can also use Closure::new to create a closure for filter composition, or Closure::from_fn to avoid the need to introduce explicit types.

Implementations

impl<F> Closure<F>

pub fn new(closure: F) -> Self

pub fn from_fn(closure: F) -> Self

where F: Fn(&Path) -> bool,

Trait Implementations

impl<F: Clone> Clone for Closure<F>

fn clone(&self) -> Closure<F>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F: Debug> Debug for Closure<F>

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

Formats the value using the given formatter.

impl<F> Filter for Closure<F>

where F: Fn(&Path, &Path) -> bool,

fn filter(&self, base_dir: &Path, directory: &Path) -> bool

Checks whether path_to_visit should be visited or not. The base_path is the initial directory provided to the visitor.

fn should_emit(&self, _: &Path) -> bool

Checks whether dir should be emitted by the iterator.

fn and<B>(self, other: B) -> And<Self, B>

where Self: Sized, B: Filter,

Creates a filter that only accepts both this and the other condition.

fn or<B>(self, other: B) -> Or<Self, B>

where Self: Sized, B: Filter,

Creates a filter that accepts this or the other condition.

fn not(self) -> Not<Self>

where Self: Sized,

Creates a filter that negates when this filter accepts.

impl<F> From<F> for Closure<F>

fn from(f: F) -> Self

Converts to this type from the input type.

impl<F: Hash> Hash for Closure<F>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<F: Ord> Ord for Closure<F>

fn cmp(&self, other: &Closure<F>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<F: PartialEq> PartialEq for Closure<F>

fn eq(&self, other: &Closure<F>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<F: PartialOrd> PartialOrd for Closure<F>

fn partial_cmp(&self, other: &Closure<F>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
