pub struct LLVMSumValue<'c>(/* private fields */);
Expand description
A Value equivalent of LLVMSumType
. Represents a HugrSumType
Value on the
wire, offering functions for inspecting and deconstructing such Values.
Implementations§
Source§impl<'c> LLVMSumValue<'c>
impl<'c> LLVMSumValue<'c>
pub fn try_new( value: impl BasicValue<'c>, sum_type: LLVMSumType<'c>, ) -> Result<Self>
pub fn get_type(&self) -> LLVMSumType<'c>
Sourcepub fn build_get_tag(&self, builder: &Builder<'c>) -> Result<IntValue<'c>>
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
.
Sourcepub fn build_untag(
&self,
builder: &Builder<'c>,
tag: usize,
) -> Result<Vec<BasicValueEnum<'c>>>
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.
pub fn build_destructure( &self, builder: &Builder<'c>, handler: impl FnMut(&Builder<'c>, usize, Vec<BasicValueEnum<'c>>) -> Result<()>, ) -> Result<()>
Sourcepub fn tag_type(&self) -> IntType<'c>
pub fn tag_type(&self) -> IntType<'c>
Get the type of the value that would be returned by build_get_tag
.
Sourcepub fn num_variants(&self) -> usize
pub fn num_variants(&self) -> usize
The number of variants in the represented HugrSumType.
