Trait FromFallibleLender 

pub trait FromFallibleLender<L: IntoFallibleLender>: Sized {
    // Required method
    fn from_fallible_lender(lender: L) -> Result<Self, L::Error>;
}

A trait for creating a value from a FallibleLender.

This is the fallible counterpart to FromLender.

Examples

struct MyVec(Vec<i32>);

impl<L: IntoFallibleLender<Error = Infallible>> FromFallibleLender<L> for MyVec
where
    L::FallibleLender: for<'all> FallibleLending<'all, Lend = i32>,
{
    fn from_fallible_lender(lender: L) -> Result<Self, Infallible> {
        let mut vec = Vec::new();
        lender.into_fallible_lender().for_each(|x| {
            vec.push(x);
            Ok(())
        })?;
        Ok(MyVec(vec))
    }
}

Required Methods

fn from_fallible_lender(lender: L) -> Result<Self, L::Error>

Creates a value from a FallibleLender, returning an error if the lender produces one.

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.
