Literal API trait. See proc_macro::Literal.

This trait is implemented for Literal in proc_macro and proc_macro2 if the corresponding feature is enabled.

See also LiteralExt.

fn byte_string(bytes: &[u8]) -> Self

Byte string literal.

fn c_string(str: &CStr) -> Self

C string literal.

This method is currently unstable in proc-macro and is missing from proc-macro2, but this crate implements it in a way that works with both on stable.

fn span(&self) -> Self::Span

The span of this literal.

fn set_span(&mut self, span: Self::Span)

Set the span of this literal.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
