Trait ValueInput 

pub trait ValueInput<'src>: Input<'src> {
    // Required method
    unsafe fn next(
        cache: &mut Self::Cache,
        cursor: &mut Self::Cursor,
    ) -> Option<Self::Token>;
}

Implemented by inputs that can have produce tokens by value.

Required Methods

unsafe fn next( cache: &mut Self::Cache, cursor: &mut Self::Cursor, ) -> Option<Self::Token>

Get the next cursor from the provided one, and the next token if it exists

Safety

As with functions on Input, the cursors provided must be generated by this input.

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.
