Trait Explainable 

pub trait Explainable: Sized {
    // Required methods
    fn name() -> &'static str;
    fn from_args(args: &ExtensionArgs) -> Result<Self, ExtensionError>;
    fn to_args(&self) -> Result<ExtensionArgs, ExtensionError>;
}

Trait for types that participate in text explanations.

Required Methods

fn name() -> &'static str

Canonical textual name for this extension. This is what appears in Substrait text plans and how the registry identifies the type.

fn from_args(args: &ExtensionArgs) -> Result<Self, ExtensionError>

Parse extension arguments into this type

fn to_args(&self) -> Result<ExtensionArgs, ExtensionError>

Convert this type to extension arguments

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.
