Variants

Ok(Empty)

The commit was successfully applied.

RuleWithInvalidMatcher(RuleId)

One of the changes in the commit caused the specified rule’s matcher to be invalid for the context in which the rule will be evaluated.

For example, this could be a matcher on the ingress interface on a rule that is in a routine installed in the egress hook, or a matcher on the source address specifying an IPv4 subnet that is in an IPv6-only namespace.

RuleWithInvalidAction(RuleId)

One of the changes in the commit caused the specified rule’s action to be invalid for the context in which the rule will be evaluated.

For example, this could be a NAT action in an IP routine.

CyclicalRoutineGraph(RoutineId)

The routine graph forms a cycle, including (at least) the specified routine.

Each uninstalled routine and all of the routines it directly or transitively jumps to must form a DAG.

ErrorOnChange(Vec<CommitError>)

At least one of the changes provided was invalid given the current state when Commit was called. In order to be maximally informative, a vector of results is returned where each result corresponds to the change at the same index (across all batches of pending changes).

TransparentProxyWithInvalidMatcher(RuleId)

A rule has a TransparentProxy action without a corresponding valid matcher: the rule must match on transport protocol to ensure that the packet has either a TCP or UDP header.

RedirectWithInvalidMatcher(RuleId)

A rule has a Redirect action without a corresponding valid matcher: if the action specifies a destination port, the rule must match on transport protocol to ensure that the packet has either a TCP or UDP header.

MasqueradeWithInvalidMatcher(RuleId)

A rule has a Masquerade action without a corresponding valid matcher: if the action specifies a source port, the rule must match on transport protocol to ensure that the packet has either a TCP or UDP header.

Implementations

impl CommitResult

pub fn ordinal(&self) -> u64

pub fn unknown_variant_for_testing() -> Self

pub fn is_unknown(&self) -> bool

Trait Implementations

impl Debug for CommitResult

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Decode<CommitResult, DefaultFuchsiaResourceDialect> for CommitResult

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, DefaultFuchsiaResourceDialect>, offset: usize, depth: Depth, ) -> Result<()>

Decodes an object of type T from the decoder’s buffers into self.

impl Encode<CommitResult, DefaultFuchsiaResourceDialect> for &mut CommitResult

unsafe fn encode( self, encoder: &mut Encoder<'_, DefaultFuchsiaResourceDialect>, offset: usize, _depth: Depth, ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for CommitResult

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ResourceTypeMarker for CommitResult

type Borrowed<'a> = &'a mut CommitResult

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &mut Self::Owned. There are three cases:

fn take_or_borrow<'a>( value: &'a mut <Self as TypeMarker>::Owned, ) -> Self::Borrowed<'a>

Cheaply converts from &mut Self::Owned to Self::Borrowed. For HandleBased types this is “take” (it returns an owned handle and replaces value with Handle::invalid), and for all other types it is “borrow” (just converts from one reference to another).

impl TypeMarker for CommitResult

type Owned = CommitResult

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.
