Methods

impl BlockAttr

pub const UNEXPECTED: BlockAttr

NONLOCAL_RETURN: BlockAttr = BlockAttr{bits: 16384,}

The block is the landing pad for longjmp.

pub const EXCEPTIONAL: BlockAttr

EXCEPTIONAL: BlockAttr = BlockAttr{bits: 32768,}

The block starts as a catch block.

pub fn from_bits_truncate(bits: u16) -> BlockAttr

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: BlockAttr) -> bool

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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

impl BlockAttr

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

Converts an integer read from GCNO to this attribute.

Errors

Returns UnsupportedAttr if the GCNO flag is unrecognized.
