Enum syn::Lit [] [src]

pub enum Lit {
    Str(LitStr),
    ByteStr(LitByteStr),
    Byte(LitByte),

Variants

A UTF-8 string literal: "foo".

A floating point literal: 1f64 or 1.0e10f64.

Must be finite. May not be infinte or NaN.

Methods

impl Lit
[src]

[src]

Interpret a Syn literal from a proc-macro2 literal.

Not all proc-macro2 literals are valid Syn literals. In particular, doc comments are considered by proc-macro2 to be literals but in Syn they are Attribute.

Panics

Panics if the input is a doc comment literal.
