[−][src]Macro error_chain::ensure
Exits a function early with an error if the condition is not satisfied
The ensure!
macro is a convenience helper that provides a way to exit
a function with an error if the given condition fails.
As an example, ensure!(condition, "error code: {}", errcode)
is equivalent to
if !condition { bail!("error code: {}", errcode); }
See documentation for bail!
macro for further details.
