Enum regex_syntax::ast::HexLiteralKind

pub enum HexLiteralKind {
    X,
    UnicodeShort,
    UnicodeLong,
}

The type of a Unicode hex literal.

Note that all variants behave the same when used with brackets. They only differ when used without brackets in the number of hex digits that must follow.

Variants

X

A \x prefix. When used without brackets, this form is limited to two digits.

UnicodeShort

A \u prefix. When used without brackets, this form is limited to four digits.

UnicodeLong

A \U prefix. When used without brackets, this form is limited to eight digits.

Implementations

impl HexLiteralKind

pub fn digits(&self) -> u32

The number of digits that must be used with this literal form when used without brackets. When used with brackets, there is no restriction on the number of digits.

Trait Implementations

impl Clone for HexLiteralKind

fn clone(&self) -> HexLiteralKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HexLiteralKind

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

Formats the value using the given formatter.

impl PartialEq for HexLiteralKind

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

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

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

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