Trait TupleTryInto 

pub trait TupleTryInto<T, E> {
    // Required method
    fn tuple_try_into(self) -> Result<T, E>;
}

A trait for fallibly converting a tuple into another tuple type.

This trait allows converting tuples into other tuple types where each element can be converted using the standard TryFrom trait. The error type E must implement From for each individual TryFrom error in the tuple, allowing error accumulation.

Part of the tuplities crate.

Required Methods

fn tuple_try_into(self) -> Result<T, E>

Attempts to convert self into T.

Errors

Returns an error of type E if any element conversion fails.

Examples

use tuplities_try_from::TupleTryInto;

let source = (1u32, 2u32);
let target: Result<(u8, u8), _> = TupleTryInto::<(u8, u8), std::num::TryFromIntError>::tuple_try_into(source);
assert_eq!(target, Ok((1, 2)));

let invalid = (300u32, 2u32); // 300 is too big for u8
let result: Result<(u8, u8), _> = TupleTryInto::<(u8, u8), std::num::TryFromIntError>::tuple_try_into(invalid);
assert!(result.is_err());
