Implementations

impl<T> Flexible<'_, T>

pub fn is_ok(&self) -> bool

Returns whether the flexible response is Ok.

pub fn is_framework_err(&self) -> bool

Returns whether the flexible response is FrameworkErr.

pub fn ok(&self) -> Option<&T>

Returns the Ok value of the response, if any.

pub fn framework_err(&self) -> Option<FrameworkError>

Returns the FrameworkErr value of the response, if any.

pub fn unwrap(&self) -> &T

Returns the contained Ok value.

Panics if the response was not Ok.

pub fn unwrap_framework_err(&self) -> FrameworkError

Returns the contained FrameworkErr value.

Panics if the response was not FrameworkErr.

pub fn as_ref(&self) -> Flexible<&T>

Returns a Flexible of a reference to the value or framework error.

pub fn as_result(&self) -> Result<&T, FrameworkError>

Returns a Result of the Ok value and a potential FrameworkError.

pub fn to_flexible(self) -> Flexible<T>

Returns a Flexible of an Owned value or framework error.
