Struct cranelift_isle::ir::ExprSequence

pub struct ExprSequence {
    pub insts: Vec<ExprInst>,
    pub pos: Pos,
}

A linear sequence of instructions that produce a new value from the right-hand side of a rule, given bindings that come from a Pattern derived from the left-hand side.

Fields

insts: Vec<ExprInst>

Instruction sequence for expression.

InstId indexes into this sequence for Value::Expr values.

pos: Pos

Position at which the rule producing this sequence was located.

Implementations

impl ExprSequence

pub fn is_const_int(&self) -> Option<(TypeId, i64)>

Is this expression sequence producing a constant integer?

If so, return the integer type and the constant.

Trait Implementations

impl Clone for ExprSequence

fn clone(&self) -> ExprSequence

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExprSequence

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

Formats the value using the given formatter.

impl Default for ExprSequence

fn default() -> ExprSequence

Returns the “default value” for a type.

impl Hash for ExprSequence

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Ord for ExprSequence

fn cmp(&self, other: &ExprSequence) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<ExprSequence> for ExprSequence

fn eq(&self, other: &ExprSequence) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ExprSequence) -> bool

This method tests for !=.

impl PartialOrd<ExprSequence> for ExprSequence

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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