std::convert::TryFrom - Rust
Description: API documentation for the Rust `TryFrom` trait in crate `std`.
Keywords: rust, rustlang, rust-lang, TryFrom

# 1.34.0[−][src]Trait std::convert::TryFrom

    pub trait TryFrom<T> {
        type Error;
        fn try_from(value: T) -> Result<Self, Self::Error>;
    }

Simple and safe type conversions that may fail in a controlled way under some circumstances. It is the reciprocal of `TryInto`.

This is useful when you are doing a type conversion that may trivially succeed but may also need special handling. For example, there is no way to convert an `i64` into an `i32` using the `From` trait, because an `i64` may contain a value that an `i32` cannot represent and so the conversion would lose data. This might be handled by truncating the `i64` to an `i32` (essentially giving the `i64`'s value modulo `i32::MAX`) or by simply returning `i32::MAX`, or by some other method. The `From` trait is intended for perfect conversions, so the `TryFrom` trait informs the programmer when a type conversion could go bad and lets them decide how to handle it.

# Generic Implementations

- `TryFrom<T> for U` implies `TryInto``<U> for T`
- `try_from` is reflexive, which means that `TryFrom<T> for T` is implemented and cannot fail -- the associated `Error` type for calling `T::try_from()` on a value of type `T` is `Infallible`. When the `!` type is stablized `Infallible` and `!` will be equivalent.

`TryFrom<T>` can be implemented as follows:

    use std::convert::TryFrom;

    struct SuperiorThanZero(i32);

    impl TryFrom<i32> for SuperiorThanZero {
        type Error = &'static str;

        fn try_from(value: i32) -> Result<Self, Self::Error> {
            if value < 0 {
                Err("SuperiorThanZero only accepts value superior than zero!")
            } else {
                Ok(SuperiorThanZero(value))
            }
        }
    }Run

# Examples

As described, `i32` implements `TryFrom<i64>`:

    use std::convert::TryFrom;

    let big_number = 1_000_000_000_000i64;
    // Silently truncates `big_number`, requires detecting
    // and handling the truncation after the fact.
    let smaller_number = big_number as i32;
    assert_eq!(smaller_number, -727379968);

    // Returns an error because `big_number` is too big to
    // fit in an `i32`.
    let try_smaller_number = i32::try_from(big_number);
    assert!(try_smaller_number.is_err());

    // Returns `Ok(3)`.
    let try_successful_smaller_number = i32::try_from(3);
    assert!(try_successful_smaller_number.is_ok());Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
