Trait Parse 

pub trait Parse: Sized {
    // Required method
    fn parse(input: ParseStream<'_>) -> Result<Self>;
}

Parsing interface implemented by all types that can be parsed in a default way from a token stream.

Refer to the module documentation for details about implementing and using the Parse trait.

Required Methods

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

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.
