Struct libflate::finish::Finish [−][src]
Finish
is a type that represents a value which
may have an error occurred during the computation.
Logically, Finish<T, E>
is equivalent to Result<T, (T, E)>
.
Implementations
impl<T, E> Finish<T, E>
[src]
pub fn new(value: T, error: Option<E>) -> Self
[src]
Makes a new instance.
Examples
use libflate::Finish; // The result value of a succeeded computation let succeeded = Finish::new("value", None as Option<()>); assert_eq!(succeeded.into_result(), Ok("value")); // The result value of a failed computation let failed = Finish::new("value", Some("error")); assert_eq!(failed.into_result(), Err("error"));
pub fn unwrap(self) -> (T, Option<E>)
[src]
Unwraps the instance.
Examples
use libflate::Finish; let succeeded = Finish::new("value", None as Option<()>); assert_eq!(succeeded.unwrap(), ("value", None)); let failed = Finish::new("value", Some("error")); assert_eq!(failed.unwrap(), ("value", Some("error")));
pub fn into_result(self) -> Result<T, E>
[src]
Converts from Finish<T, E>
to Result<T, E>
.
Examples
use libflate::Finish; let succeeded = Finish::new("value", None as Option<()>); assert_eq!(succeeded.into_result(), Ok("value")); let failed = Finish::new("value", Some("error")); assert_eq!(failed.into_result(), Err("error"));
pub fn as_result(&self) -> Result<&T, &E>
[src]
Converts from Finish<T, E>
to Result<&T, &E>
.
Examples
use libflate::Finish; let succeeded = Finish::new("value", None as Option<()>); assert_eq!(succeeded.as_result(), Ok(&"value")); let failed = Finish::new("value", Some("error")); assert_eq!(failed.as_result(), Err(&"error"));
