Struct ReadDenyMatcher 

Source 
pub struct ReadDenyMatcher { /* private fields */ }
Expand description

Runtime matcher for read-deny entries in a filesystem sandbox policy.

Implementations§

Source§

impl ReadDenyMatcher

Source

pub fn new( file_system_sandbox_policy: &FileSystemSandboxPolicy, cwd: &Path, ) -> Option<Self>

Builds a matcher from exact deny-read roots and deny-read glob entries.

Returns None when the policy has no deny-read restrictions, so callers can skip read-deny checks without allocating matcher state. The cwd resolves cwd-relative policy paths and special paths before matching.

Source

pub fn try_new( file_system_sandbox_policy: &FileSystemSandboxPolicy, cwd: &Path, ) -> Result<Option<Self>, String>

Builds a matcher for callers that must reject malformed glob patterns.

Runtime read checks intentionally fail closed on malformed deny patterns. Host-side expansion work should use this constructor instead so a typo cannot broaden the set of paths it mutates before execution starts.

Source

pub fn is_read_denied(&self, path: &Path) -> bool

Returns whether path is denied by the policy used to build this matcher.
