Struct cov::raw::ArcAttr

pub struct ArcAttr { /* fields omitted */ }

Attributes about an Arc.

Methods

impl ArcAttr

pub const ON_TREE: ArcAttr

ON_TREE: ArcAttr = ArcAttr{bits: 1,}

The arc is a non-instrumentable edge on the spanning tree. This arc will not appear in the corresponding GCDA file.

Equivalent to the GCOV_ARC_ON_TREE flag.

pub const FAKE: ArcAttr

FAKE: ArcAttr = ArcAttr{bits: 2,}

The arc is fake. Such arcs connect no-return blocks (e.g. infinite loop and -> ! functions) to the exit block, i.e. in reality this arc should never be taken.

Equivalent to the GCOV_ARC_FAKE flag.

pub const FALLTHROUGH: ArcAttr

FALLTHROUGH: ArcAttr = ArcAttr{bits: 4,}

The arc is fall-through.

Equivalent to the GCOV_ARC_FALLTHROUGH flag.

pub const THROW: ArcAttr

THROW: ArcAttr = ArcAttr{bits: 16,}

The arc is taken to a catch handler.

pub const CALL_NON_RETURN: ArcAttr

CALL_NON_RETURN: ArcAttr = ArcAttr{bits: 32,}

The arc is for a function that abnormally returns.

pub const NONLOCAL_RETURN: ArcAttr

NONLOCAL_RETURN: ArcAttr = ArcAttr{bits: 64,}

The arc is for setjmp.

pub const UNCONDITIONAL: ArcAttr

UNCONDITIONAL: ArcAttr = ArcAttr{bits: 128,}

The arc is an unconditional branch.

pub fn empty() -> ArcAttr

Returns an empty set of flags.

pub fn all() -> ArcAttr

Returns the set containing all flags.

pub fn bits(&self) -> u16

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u16) -> Option<ArcAttr>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub fn from_bits_truncate(bits: u16) -> ArcAttr

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub fn intersects(&self, other: ArcAttr) -> bool

Returns true if there are flags common to both self and other.

pub fn contains(&self, other: ArcAttr) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: ArcAttr)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: ArcAttr)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: ArcAttr)

Toggles the specified flags in-place.

pub fn set(&mut self, other: ArcAttr, value: bool)

Inserts or removes the specified flags depending on the passed value.

impl ArcAttr

pub fn from_gcno(flags: u32) -> Result<ArcAttr>

Converts an integer read from GCNO to this attribute.

Errors

Returns UnsupportedAttr if the GCNO flag is unrecognized.
