// Converts an [error] into a human-friendly string representation.

|
//
|
|
// Note that this strerror implementation lacks any context-specific information
|
|
// about the error types supported. For example, [exists] is stringified as "An
|
|
// attempt was made to create a resource which already exists", but if source of
|
|
// the error is, say, creating a file, it would likely be more appropriate to
|
|
// use the term "file" rather than "resource". For this reason, it is preferred
|
|
// that modules which return an error type from this module provide their own
|
|
// strerror function which provides more context-appropriate error messages for
|
|
// each of those types.
