Trait TryFromList 

pub trait TryFromList: Sized {
    type Error;

    // Required method
    fn try_from_list(list: List) -> Result<Self, Self::Error>;
}

Fallible conversion from an R list into a Rust value.

Required Associated Types

type Error

Error returned when conversion fails.

Required Methods

fn try_from_list(list: List) -> Result<Self, Self::Error>

Attempt to convert an R list wrapper into Self.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
