Implementations

source

impl DataValue

source

pub fn from_integer(
imm: i128,
ty: Type
) -> Result<DataValue, DataValueCastFailure>

Try to cast an immediate integer (a wrapped i64 on most Cranelift instructions) to the given Cranelift Type.

source

pub fn ty(&self) -> Type

Return the Cranelift IR Type for this DataValue.

source

pub fn is_vector(&self) -> bool

Return true if the value is a vector (i.e. DataValue::V128).

source

pub fn is_bool(&self) -> bool

Return true if the value is a bool (i.e. DataValue::B).

source

pub fn write_to_slice(&self, dst: &mut [u8 ])

Write a DataValue to a slice.

Panics:

Panics if the slice does not have enough space to accommodate the DataValue

source

pub fn read_from_slice(src: &[u8 ], ty: Type) -> Self

Read a DataValue from a slice using a given Type.

Panics:

Panics if the slice does not have enough space to accommodate the DataValue

source

pub unsafe fn write_value_to(&self, p: *mut u128)

Write a DataValue to a memory location.

source

pub unsafe fn read_value_from(p: *const u128, ty: Type) -> Self

Read a DataValue from a memory location using a given Type.

source

pub fn bitwise_eq(&self, other: &DataValue) -> bool

Performs a bitwise comparison over the contents of DataValue.

Returns true if all bits are equal.

This behaviour is different from PartialEq for NaN floats.
