pub trait TryFrom<Src>: Sized {
type Err: Error;
// Required method
fn try_from(src: Src) -> Result<Self, Self::Err>;
}Expand description
This trait is used to perform a conversion between different semantic types which might fail.
Where possible, prefer implementing this trait over TryInto, but prefer using TryInto for generic constraints.
§Details
Typically, this should be used in cases where you are converting between values whose ranges and/or representations only partially overlap. That the conversion may fail should be a reasonably expected outcome. A standard example of this is converting from integers to enums of unitary variants.

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.
