Struct jlrs::value::union::Union

#[repr(transparent)]pub struct Union<'frame>(_, _);

A struct field can have a type that's a union of several types. In this case, the type of this field is an instance of Union.

Implementations

impl<'frame> Union<'frame>

pub fn isbitsunion(self) -> bool

Returns true if all the isbits union optimization applies to this union type.

pub fn isbits_size_align(self, size: &mut usize, align: &mut usize) -> bool

Returns true if the isbits union optimization applies to this union type and calculates the size and aligment if it does. If this method returns false, the calculated size and alignment are invalid.

pub fn size(self) -> usize

Returns the size of a field that is of this Union type excluding the flag that is used in bits unions.

pub fn a(self) -> Value<'frame, 'static>

Unions are stored as binary trees, the arguments are stored as its leaves. This method returns one of its branches.

pub fn b(self) -> Value<'frame, 'static>

Unions are stored as binary trees, the arguments are stored as its leaves. This method returns one of its branches.

pub fn as_value(self) -> Value<'frame, 'static>

Convert self to a Value.
