Enum HoldBit 

pub(crate) enum HoldBit {
    Unspecified,
    Hold,
    NotHold,
}

Indicates whether the hold bit is set, cleared or unspecified.

The hold bit is bit 4.9 of the instruction word (see section 6-2 of the Users Handbook).

The effect of the hold bit is explained in section 4-3.2 of the Users Handbook.

Variants

Unspecified

The value of the hold bit was not specified.

Hold

The hold bit should be set.

NotHold

The hold bit should be cleared. The user might want to do this because some opcodes (LDE, ITE, JPX, JNX) would otherwise automatically set it.

Trait Implementations

impl Clone for HoldBit

fn clone(&self) -> HoldBit

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HoldBit

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

Formats the value using the given formatter.

impl PartialEq for HoldBit

fn eq(&self, other: &HoldBit) -> 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.
