Struct Inst 

pub struct Inst(/* private fields */);

An instruction of a function, numbered in creation order across all blocks.

Examples

use backend_lang::mir::{Function, Operand};
use backend_lang::x86_64::{op, SYSV};

let mut f = Function::new("f", &SYSV);
let b = f.block()?;
let i = f.push(b, op::RET, &[])?;
assert_eq!(i.to_string(), "inst0");

Implementations

impl Inst

pub const fn new(index: u32) -> Inst

The id with index index. Whether a function has it is checked where it is used.

Examples

use backend_lang::mir::Inst;

assert_eq!(Inst::new(3).index(), 3);

pub const fn index(self) -> usize

The id’s index.

Examples

use backend_lang::mir::Function;
use backend_lang::x86_64::{op, SYSV};
let mut f = Function::new("f", &SYSV);
let b = f.block()?;
assert_eq!(f.push(b, op::RET, &[])?.index(), 0);

Trait Implementations

impl Clone for Inst

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Inst

impl Debug for Inst

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

Formats the value using the given formatter.

impl Display for Inst

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

Formats the value using the given formatter.

impl Eq for Inst

impl Hash for Inst

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Inst

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Inst

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Inst

fn partial_cmp(&self, other: &Self) -> 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.
