Struct shellexpand::LookupError
source · pub struct LookupError<E> {
pub var_name: String,
pub cause: E,
}
Expand description
Represents a variable lookup error.
This error is returned by env_with_context()
function (and, therefore, also by env()
,
full_with_context()
and full()
) when the provided context function returns an error. The
original error is provided in the cause
field, while name
contains the name of a variable
whose expansion caused the error.
Fields§
§var_name: String
The name of the problematic variable inside the input string.
cause: E
The original error returned by the context function.
