NSTDResult

Enum NSTDResult 

Source
#[repr(C, u8)]
pub enum NSTDResult<T, E> { Err(E), Ok(T), }
Available on crate feature core only.
Expand description

Defines a “result” type with success and error variants.

Variants§

§

Err(E)

The error variant.

§

Ok(T)

The success variant.

Implementations§

Source§

impl<T, E> NSTDResult<T, E>

Source

pub fn unwrap(self) -> T

Attempts to return the contained Ok value in an NSTDResult.

This operation is only useful for testing code, it’s use in production should be discouraged.

§Panics

Panics if self is an Err value.

Source

pub fn expect(self, msg: &str) -> T

Attempts to return the contained Ok value in an NSTDResult.

§Panics

Panics with msg if self is an Err value.
