1.34.0[−][src]Trait core::convert::TryFrom
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
impliesTryInto
<U> for T
try_from
is reflexive, which means thatTryFrom<T> for T
is implemented and cannot fail -- the associatedError
type for callingT::try_from()
on a value of typeT
isInfallible
. When the!
type is stabilizedInfallible
and!
will be equivalent.
TryFrom<T>
can be implemented as follows:
use std::convert::TryFrom; struct GreaterThanZero(i32); impl TryFrom<i32> for GreaterThanZero { type Error = &'static str; fn try_from(value: i32) -> Result<Self, Self::Error> { if value <= 0 { Err("GreaterThanZero only accepts value superior than zero!") } else { Ok(GreaterThanZero(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
