Trait Textify 

pub trait Textify {
    // Required methods
    fn textify<S: Scope, W: Write>(&self, ctx: &S, w: &mut W) -> Result;
    fn name() -> &'static str;
}

A trait for types that can be output in text format.

This trait is used to convert a Substrait type into a string representation that can be written to a text writer.

Required Methods

fn textify<S: Scope, W: Write>(&self, ctx: &S, w: &mut W) -> Result

fn name() -> &'static str

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.
