Struct ClassBytes

impl ClassBytes

fn new<I>(ranges: I) -> ClassBytes
where
    I: IntoIterator<Item = ClassBytesRange>

Create a new class from a sequence of ranges.

The given ranges do not need to be in any specific order, and ranges may overlap. Ranges will automatically be sorted into a canonical non-overlapping order.

fn empty() -> ClassBytes

Create a new class with no ranges.

An empty class matches nothing. That is, it is equivalent to Hir::fail.

fn push(self: &mut Self, range: ClassBytesRange)

Add a new range to this set.

fn iter(self: &Self) -> ClassBytesIter<'_>

Return an iterator over all ranges in this class.

The iterator yields ranges in ascending order.

fn ranges(self: &Self) -> &[ClassBytesRange]

Return the underlying ranges as a slice.

fn case_fold_simple(self: &mut Self)

Expand this character class such that it contains all case folded characters. For example, if this class consists of the range a-z, then applying case folding will result in the class containing both the ranges a-z and A-Z.

Note that this only applies ASCII case folding, which is limited to the characters a-z and A-Z.

fn negate(self: &mut Self)

Negate this byte class.

For all b where b is a any byte, if b was in this set, then it will not be in this set after negation.

fn union(self: &mut Self, other: &ClassBytes)

Union this byte class with the given byte class, in place.

fn intersect(self: &mut Self, other: &ClassBytes)

Intersect this byte class with the given byte class, in place.

fn difference(self: &mut Self, other: &ClassBytes)

Subtract the given byte class from this byte class, in place.

fn symmetric_difference(self: &mut Self, other: &ClassBytes)

Compute the symmetric difference of the given byte classes, in place.

This computes the symmetric difference of two byte classes. This removes all elements in this class that are also in the given class, but all adds all elements from the given class that aren't in this class. That is, the class will contain all elements in either class, but will not contain any elements that are in both classes.

fn is_ascii(self: &Self) -> bool

Returns true if and only if this character class will either match nothing or only ASCII bytes. Stated differently, this returns false if and only if this class contains a non-ASCII byte.

fn minimum_len(self: &Self) -> Option<usize>

Returns the length, in bytes, of the smallest string matched by this character class.

Returns None when the class is empty.

fn maximum_len(self: &Self) -> Option<usize>

Returns the length, in bytes, of the longest string matched by this character class.

Returns None when the class is empty.

fn literal(self: &Self) -> Option<Vec<u8>>

If this class consists of exactly one byte, then return it as a literal byte string.

If this class is empty or contains more than one byte, then None is returned.

fn to_unicode_class(self: &Self) -> Option<ClassUnicode>

If this class consists of only ASCII ranges, then return its corresponding and equivalent Unicode class.
