Trait Substitutor 

pub trait Substitutor {
    // Required methods
    fn new() -> Self;
    fn gsub<'a>(&self, s: &'a str) -> Cow<'a, str>;
    fn add(
        &mut self,
        pattern: &str,
        repl: String,
        limit: usize,
    ) -> Result<(), SubstitutorAddError>;
}

The substitutor implementing the gsub function in tphrase. You can replace the default into your version. Generator doesn’t have Clone and Debug traits if your instance of Substitutor doesn’t have Clone and Debug traits.

Required Methods

fn new() -> Self

Create a substitutor. Used in parse(), parse_str(), Generator::from_str(), and Syntax::from_str().

fn gsub<'a>(&self, s: &'a str) -> Cow<'a, str>

Substitute str. Used in Generator::generate().

fn add( &mut self, pattern: &str, repl: String, limit: usize, ) -> Result<(), SubstitutorAddError>

Add an instruction of gsub function. Used in parsing.

The string in Err is the error message to show users.

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.
