Enum PathFailure 

#[non_exhaustive]
pub enum PathFailure {
    EmptyPath,
    InteriorNul,
    PathTooLong,
    NotFullyQualified,
    PathResolution,
}

Why a caller’s path could not be prepared.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EmptyPath

The path had no code units. An empty path names nothing.

InteriorNul

The path contained an interior NUL. Win32 would stop at it and open a different, shorter path than the caller named.

PathTooLong

An ordinary path, or the fully qualified form it resolved to, did not fit the ordinary MAX_PATH limit including its terminator.

This limit is deliberate rather than incidental: it keeps behaviour independent of the host executable’s longPathAware manifest. Supply a fully qualified \?\ path to name a longer one.

NotFullyQualified

A \?\ path was not fully qualified, so Win32 would not interpret it as the verbatim absolute path that prefix promises.

PathResolution

Windows could not resolve an ordinary path to its fully qualified form.
