pub struct OutputFlags(/* private fields */);
Expand description
Specifies how a fuzzing engine should configure output streams.
Flags may be combined, e.g. CLOSE_STDOUT | CLOSE_STDERR
. Support for each
flag is engine-specific. Specifying an unsupported output mode flag may
cause Controller.Configure
to return ZX_ERR_NOT_SUPPORTED
.
Implementations§
Source§impl OutputFlags
impl OutputFlags
Sourcepub const CLOSE_STDOUT: Self = _
pub const CLOSE_STDOUT: Self = _
Suppress standard output from the engine process. This is analogous to
libFuzzer’s -close_fd_mask=1
.
Sourcepub const CLOSE_STDERR: Self = _
pub const CLOSE_STDERR: Self = _
Suppress standard error from the engine process. Use with care: this may
remove diagnostic output from the target code (e.g. messages on assert
failure). This is analogous to libFuzzer’s -close_fd_mask=2
.

Sourcepub const fn bits(&self) -> u32
pub const fn bits(&self) -> u32
Get the underlying bits value.
The returned value is exactly the bits set in this flags value.
Sourcepub const fn from_bits(bits: u32) -> Option<Self>
pub const fn from_bits(bits: u32) -> Option<Self>
Convert from a bits value.
This method will return None
if any unknown bits are set.
Sourcepub const fn from_bits_truncate(bits: u32) -> Self
pub const fn from_bits_truncate(bits: u32) -> Self
Convert from a bits value, unsetting any unknown bits.
Sourcepub const fn from_bits_retain(bits: u32) -> Self
pub const fn from_bits_retain(bits: u32) -> Self
Convert from a bits value exactly.
Sourcepub fn from_name(name: &str) -> Option<Self>
pub fn from_name(name: &str) -> Option<Self>
Get a flags value with the bits of a flag with the given name set.
This method will return None
if name
is empty or doesn’t
correspond to any named flag.
Sourcepub const fn intersects(&self, other: Self) -> bool
pub const fn intersects(&self, other: Self) -> bool
Whether any set bits in a source flags value are also set in a target flags value.
Sourcepub const fn contains(&self, other: Self) -> bool
pub const fn contains(&self, other: Self) -> bool
Whether all set bits in a source flags value are also set in a target flags value.
Sourcepub fn remove(&mut self, other: Self)
pub fn remove(&mut self, other: Self)
The intersection of a source flags value with the complement of a target flags value (&!
).
This method is not equivalent to self & !other
when other
has unknown bits set.
remove
won’t truncate other
, but the !
operator will.
Sourcepub fn toggle(&mut self, other: Self)
pub fn toggle(&mut self, other: Self)
The bitwise exclusive-or (^
) of the bits in two flags values.
Sourcepub fn set(&mut self, other: Self, value: bool)
pub fn set(&mut self, other: Self, value: bool)
Call insert
when value
is true
or remove
when value
is false
.
Sourcepub const fn intersection(self, other: Self) -> Self
pub const fn intersection(self, other: Self) -> Self
The bitwise and (&
) of the bits in two flags values.
Sourcepub const fn union(self, other: Self) -> Self
pub const fn union(self, other: Self) -> Self
The bitwise or (|
) of the bits in two flags values.
Sourcepub const fn difference(self, other: Self) -> Self
pub const fn difference(self, other: Self) -> Self
The intersection of a source flags value with the complement of a target flags value (&!
).
This method is not equivalent to self & !other
when other
has unknown bits set.
difference
won’t truncate other
, but the !
operator will.
Sourcepub const fn symmetric_difference(self, other: Self) -> Self
pub const fn symmetric_difference(self, other: Self) -> Self
The bitwise exclusive-or (^
) of the bits in two flags values.
Sourcepub const fn complement(self) -> Self
pub const fn complement(self) -> Self
The bitwise negation (!
) of the bits in a flags value, truncating the result.
Source§impl OutputFlags
impl OutputFlags
Sourcepub const fn iter(&self) -> Iter<OutputFlags>
pub const fn iter(&self) -> Iter<OutputFlags>
Yield a set of contained flags values.
Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.
Sourcepub const fn iter_names(&self) -> IterNames<OutputFlags>
pub const fn iter_names(&self) -> IterNames<OutputFlags>
Yield a set of contained named flags values.
This method is like iter
, except only yields bits in contained named flags.
Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
