Struct stdcli::prelude::shellexpand::LookupError

pub struct LookupError<E> {
    pub var_name: String,
    pub cause: E,
}

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.
