pub struct BoundedScope<'a>(/* private fields */);Expand description
Validated, non-empty TLV sequence of permissions.
Each entry has the layout:
[res_len: u8][resource bytes][verb_len: u8][verb bytes]try_new walks the slice and verifies that:
- the slice is non-empty,
- every entry is complete (no truncated fields),
- the total number of entries does not exceed
MAX_SCOPE_PERMS.
After construction the slice is guaranteed to be fully consumed by
well-formed entries and iterable via iter().
Implementations§
Source§impl<'a> BoundedScope<'a>
impl<'a> BoundedScope<'a>
Sourcepub fn iter(&self) -> ScopeIter<'a> ⓘ
pub fn iter(&self) -> ScopeIter<'a> ⓘ
Returns an iterator yielding (resource, verb) pairs in order.
Sourcepub fn try_new(raw: &'a [u8]) -> Result<Self, KernelError>
pub fn try_new(raw: &'a [u8]) -> Result<Self, KernelError>
Parses and validates a raw TLV slice.
Returns ScopeEmpty if raw is empty, WireInvalid if any entry is
truncated or structurally incorrect, and ScopeTooLarge if the entry
count exceeds MAX_SCOPE_PERMS.
