Struct ChoiceFlags 

pub struct ChoiceFlags {
    pub has_condition: bool,
    pub has_start_content: bool,
    pub has_choice_only_content: bool,
    pub once_only: bool,
    pub is_invisible_default: bool,
}

Flags packed into a BeginChoice instruction.

Under the single-pop protocol, BeginChoice pops at most one display string from the stack when has_start_content || has_choice_only_content. The two content flags are metadata indicating which parts of the original ink choice contributed to that string — the runtime does not pop them separately.

Fields

has_condition: bool

has_start_content: bool

Original choice had start content (text before [).

has_choice_only_content: bool

Original choice had choice_only content (text inside []). Under the single-pop protocol this is metadata only — no extra stack pop.

once_only: bool

is_invisible_default: bool

Trait Implementations

impl Clone for ChoiceFlags

fn clone(&self) -> ChoiceFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ChoiceFlags

impl Debug for ChoiceFlags

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

Formats the value using the given formatter.

impl Eq for ChoiceFlags

impl Hash for ChoiceFlags

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ChoiceFlags

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