pub struct ClassBytes { /* fields omitted */ }
A set of characters represented by arbitrary bytes (where one byte
corresponds to one character).
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.
Create a new class with no ranges.
Add a new range to this set.
Return an iterator over all ranges in this class.
The iterator yields ranges in ascending order.
Return the underlying ranges as a slice.
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
.
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.
Union this byte class with the given byte class, in place.
Intersect this byte class with the given byte class, in place.
Subtract the given byte class from this byte class, in place.
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.
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.
