Trait TryConvert 

pub trait TryConvert<'ast, T>
where
    Self: Sized,
{
    type Error;

    // Required method
    fn try_convert(alloc: &'ast AstAlloc, from: T) -> Result<Self, Self::Error>;
}

Similar to TryFrom, but takes an additional allocator for conversion from and to crate::ast::Ast that requires to thread an explicit allocator.

We chose a different name than try_from for the method - although it has a different signature from the standard TryFrom (two arguments vs one) - to avoid confusing the compiler which would otherwise have difficulties disambiguating calls like Ast::try_from.

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.
