Struct Transcriber 

pub struct Transcriber { /* private fields */ }

Replacement pattern.

Transcriber corresponds to MacroTranscriber (excluding outermost brace) in Macros By Example.

A Transcriber created using FromStr::from_str preserves whitespace in the original string as much as possible.

Implementations

impl Transcriber

pub fn parse(input: ParseStream<'_>) -> Result<Self>

Parse a transcriber.

Unlike FromStr::from_str, non-token information, such as whitespace, is lost.

Transcriber does not implement Parse to prevent information loss using parse_str.
