Enum LiteralKind

pub enum LiteralKind {
    Verbatim,
    Meta,
    Superfluous,
    Octal,
    HexFixed(HexLiteralKind),
    HexBrace(HexLiteralKind),
    Special(SpecialLiteralKind),
}

The kind of a single literal expression.

Variants

Verbatim

The literal is written verbatim, e.g., a or ☃.

Meta

The literal is written as an escape because it is otherwise a special regex meta character, e.g., \* or \[.

Superfluous

The literal is written as an escape despite the fact that the escape is unnecessary, e.g., \% or \/.

Octal

The literal is written as an octal escape, e.g., \141.

HexFixed(HexLiteralKind)

The literal is written as a hex code with a fixed number of digits depending on the type of the escape, e.g., \x61 or \u0061 or \U00000061.

HexBrace(HexLiteralKind)

The literal is written as a hex code with a bracketed number of digits. The only restriction is that the bracketed hex code must refer to a valid Unicode scalar value.

Special(SpecialLiteralKind)

The literal is written as a specially recognized escape, e.g., \f or \n.

Trait Implementations

impl Clone for LiteralKind

fn clone(&self) -> LiteralKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LiteralKind

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

Formats the value using the given formatter.

impl PartialEq for LiteralKind

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Eq for LiteralKind

impl StructuralPartialEq for LiteralKind

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
