Implementations

impl BtConstantValue

pub fn zero(bt_type: BtType) -> Self

Makes a BtConstantValue for the given type with a constant value of zero.

pub fn one(bt_type: BtType) -> Self

Makes a BtConstantValue for the given type with a constant value of 1.

pub fn get_bt_type(&self) -> BtType

Gets the IR type of the constant value.

pub fn is_truthy(&self) -> bool

Returns whether the constant value evaluates to true when used in a boolean context.

In general, the function returns true if the value is non-zero. For Float32/64 values of -0.0, this function returns false.

Trait Implementations

impl Clone for BtConstantValue

fn clone(&self) -> BtConstantValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BtConstantValue

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

Formats the value using the given formatter.

impl Display for BtConstantValue

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

Formats the value using the given formatter.

impl From<AstConstantFp> for BtConstantValue

fn from(value: AstConstantFp) -> Self

Converts to this type from the input type.

impl From<AstConstantInteger> for BtConstantValue

fn from(value: AstConstantInteger) -> Self

Converts to this type from the input type.

impl PartialEq for BtConstantValue

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

impl PartialOrd for BtConstantValue

fn partial_cmp(&self, other: &BtConstantValue) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
