Expand description
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§
sourcefn checked_from<T>(t: T) -> Option<Self>where
Self: TryFrom<T>,
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.
sourcefn checked_into<T>(self) -> Option<T>where
Self: TryInto<T>,
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.
