[][src]Trait sr_primitives::traits::CheckedConversion

pub trait CheckedConversion {
    fn checked_from<T>(t: T) -> Option<Self>
    where
        Self: TryFrom<T>
, { ... }
fn checked_into<T>(self) -> Option<T>
    where
        Self: TryInto<T>
, { ... } }

Convenience type to work around the highly unergonomic syntax needed to invoke the functions of overloaded generic traits, in this case TryFrom and TryInto.

Provided methods

fn checked_from<T>(t: T) -> Option<Self> where
    Self: TryFrom<T>, 

Convert from a value of T into an equivalent instance of Option<Self>.

This just uses TryFrom internally but with this variant you can provide the destination type using turbofish syntax in case Rust happens not to assume the correct type.

fn checked_into<T>(self) -> Option<T> where
    Self: TryInto<T>, 

Consume self to return Some equivalent value of Option<T>.

This just uses TryInto internally but with this variant you can provide the destination type using turbofish syntax in case Rust happens not to assume the correct type.
