Trait rlua::LuaResultExt
[−]
pub trait LuaResultExt<T, E> {
fn chain_err<F, EK>(self, callback: F) -> Result<T, LuaError>
where
F: FnOnce() -> EK,
EK: Into<LuaErrorKind>;
}Additional methods for Result, for easy interaction with this crate.
Required Methods
fn chain_err<F, EK>(self, callback: F) -> Result<T, LuaError> where
F: FnOnce() -> EK,
EK: Into<LuaErrorKind>,
F: FnOnce() -> EK,
EK: Into<LuaErrorKind>,
If the Result is an Err then chain_err evaluates the closure,
which returns some type that can be converted to ErrorKind, boxes
the original error to store as the cause, then returns a new error
containing the original error.
