impl Fail for SysctlError

fn name(&self) -> Option<&str>

Returns the “name” of the error.

fn cause(&self) -> Option<&dyn Fail>

pub fn context<D>(self, context: D) -> Context<D> where
    D: Display + Send + Sync + 'static, 

Provides context for this failure.

pub fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.
