Implementations§

Source§

impl<'c> LLVMSumValue<'c>

Source

pub fn try_new( value: impl BasicValue<'c>, sum_type: LLVMSumType<'c>, ) -> Result<Self>

Source

pub fn get_type(&self) -> LLVMSumType<'c>

Source

pub fn build_get_tag(&self, builder: &Builder<'c>) -> Result<IntValue<'c>>

Emit instructions to read the tag of a value of type LLVMSumType.

The type of the value is that returned by LLVMSumType::tag_type.

Source

pub fn build_untag( &self, builder: &Builder<'c>, tag: usize, ) -> Result<Vec<BasicValueEnum<'c>>>

Emit instructions to read the inner values of a value of type LLVMSumType, on the assumption that it’s tag is tag.

If it’s tag is not tag, the returned values are unspecified.

Source

pub fn build_destructure( &self, builder: &Builder<'c>, handler: impl FnMut(&Builder<'c>, usize, Vec<BasicValueEnum<'c>>) -> Result<()>, ) -> Result<()>

Source

pub fn tag_type(&self) -> IntType<'c>

Get the type of the value that would be returned by build_get_tag.

Source

pub fn num_variants(&self) -> usize

The number of variants in the represented HugrSumType.
