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".

Keys are the element names; an element without a usable name (no names attribute, NA, or not valid UTF-8) is keyed by its 0-based position, and empty names share the key "" (the last one wins). A non-empty name that appears more than once is an error (SexpError::DuplicateName), as for the TryFromSexp map conversion.
