SymlinkPolicy

rama::utils::fs

Enum SymlinkPolicy 

#[non_exhaustive]
pub enum SymlinkPolicy {
    RestrictToRoot,
    Allow,
}
Available on crate feature std only.
Expand description

How symbolic links are treated when opening a file confined to a root directory via OpenOptions::jail or OpenOptionsSync::jail.

Symlink handling only applies when a jail root is set; without one there is no boundary to confine to.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

RestrictToRoot

Symlinks may be followed, but the fully resolved path must stay within the jail root. A symlink that resolves outside the root is rejected with UnsafePathError::EscapesRoot. This is the default.

§

Allow

Symlinks are followed even when they resolve outside the jail root. The lexical confinement (no .., no absolute paths) still applies, but the resolved target is not checked against the root. Opt in only when the linked targets are trusted.
