Enum HexLiteralKind

Source
pub enum HexLiteralKind {
    X,
    UnicodeShort,
    UnicodeLong,
}
Expand description

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§

Source§

impl HexLiteralKind

Source

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.
