Trait Implementations

impl<'a> ArchiveContext for DefaultValidator<'a>

type PrefixRange = <ArchiveValidator<'a> as ArchiveContext>::PrefixRange

unsafe fn bounds_check_ptr( &mut self, base: *const u8, offset: isize, ) -> Result<*const u8, Self::Error>

Checks that a relative pointer points to an address within the archive.

unsafe fn bounds_check_layout( &mut self, data_address: *const u8, layout: &Layout, ) -> Result<(), Self::Error>

Checks that a given pointer can be dereferenced.

unsafe fn bounds_check_subtree_ptr_layout( &mut self, data_address: *const u8, layout: &Layout, ) -> Result<(), Self::Error>

Checks that the given data address and layout is located completely within the subtree range.

unsafe fn push_prefix_subtree_range( &mut self, root: *const u8, end: *const u8, ) -> Result<PrefixRange, Self::Error>

Pushes a new subtree range onto the validator and starts validating it.

fn pop_prefix_range(&mut self, range: PrefixRange) -> Result<(), Self::Error>

Pops the given range, restoring the original state with the pushed range removed.

unsafe fn push_suffix_subtree_range( &mut self, start: *const u8, root: *const u8, ) -> Result<SuffixRange, Self::Error>

Pushes a new subtree range onto the validator and starts validating it.

fn pop_suffix_range(&mut self, range: SuffixRange) -> Result<(), Self::Error>

Finishes the given range, restoring the original state with the pushed range removed.

fn finish(&mut self) -> Result<(), Self::Error>

Verifies that all outstanding claims have been returned.

fn wrap_layout_error(error: LayoutError) -> Self::Error

Wraps a layout error in an ArchiveContext error

unsafe fn check_ptr<T: LayoutRaw + Pointee + ?Sized>( &mut self, base: *const u8, offset: isize, metadata: T::Metadata, ) -> Result<*const T, Self::Error>

Checks that the given relative pointer to a subtree can be dereferenced.

unsafe fn check_subtree_rel_ptr<T: ArchivePointee + LayoutRaw + ?Sized>( &mut self, rel_ptr: &RelPtr<T>, ) -> Result<*const T, Self::Error>

Checks that the given RelPtr to a subtree can be dereferenced.

unsafe fn push_prefix_subtree<T: LayoutRaw + ?Sized>( &mut self, root: *const T, ) -> Result<Self::PrefixRange, Self::Error>

Pushes a new subtree range onto the validator and starts validating it.
