Struct sea_canal::Pattern

pub struct Pattern(_);

A sequence of operations defining a pattern.

Methods

impl Pattern

fn new(elems: Vec<PatternElem>) -> Self

Constructs a new pattern given a vector of operations.

fn empty() -> Self

Constructs a new empty pattern.

fn len(&self) -> usize

fn is_empty(&self) -> bool

fn extend_each<T>(&self, iter: T) -> Vec<Self> where
    T: Iterator<Item = PatternElem>, 

Appends each of the items in iter to the pattern separately, returning a vector of patterns.

let pat = pat![Plus(3), Mult(2)];
let pats = pat.extend_each(vec![Div(2), Div(3)].into_iter());
assert_eq!(pats, vec![pat![Plus(3), Mult(2), Div(2)], pat![Plus(3), Mult(2), Div(3)]]);

fn iter(&self) -> Iter<PatternElem>

fn has_repeating_types(&self) -> bool

Trait Implementations

impl Clone for Pattern

fn clone(&self) -> Pattern

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Pattern

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Hash for Pattern

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

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

Feeds a slice of this type into the given [Hasher].

impl PartialEq for Pattern

fn eq(&self, __arg_0: &Pattern) -> bool

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

fn ne(&self, __arg_0: &Pattern) -> bool

This method tests for !=.

impl Eq for Pattern

impl PartialOrd for Pattern

fn partial_cmp(&self, __arg_0: &Pattern) -> Option<Ordering>

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

fn lt(&self, __arg_0: &Pattern) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &Pattern) -> bool

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

fn gt(&self, __arg_0: &Pattern) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &Pattern) -> bool

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

impl Ord for Pattern

fn cmp(&self, __arg_0: &Pattern) -> Ordering

This method returns an Ordering between self and other.

impl IntoIterator for Pattern

type Item = PatternElem

The type of the elements being iterated over.

type IntoIter = IntoIter<PatternElem>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl FromIterator<PatternElem> for Pattern

fn from_iter<I: IntoIterator<Item = PatternElem>>(iterator: I) -> Self

Creates a value from an iterator.

impl Display for Pattern

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

Formats the value using the given formatter.
