Implementations

impl<'a> Function<'a>

pub fn new(
    linkage: Linkage,
    name: String,
    arguments: Vec<(Type<'a>, Value)>,
    return_ty: Option<Type<'a>>
) -> Self

Instantiates an empty function and returns it

pub fn add_block(&mut self, label: String) -> &mut Block<'a>

Adds a new empty block with a specified label and returns a reference to it

pub fn last_block(&mut self) -> &Block<'_>

👎Deprecated since 3.0.0: Use self.blocks.last() or self.blocks.last_mut() instead.

Returns a reference to the last block

pub fn add_instr(&mut self, instr: Instr<'a>)

Adds a new instruction to the last block

pub fn assign_instr(&mut self, temp: Value, ty: Type<'a>, instr: Instr<'a>)

Adds a new instruction assigned to a temporary

Trait Implementations

impl<'a> Clone for Function<'a>

fn clone(&self) -> Function<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Function<'a>

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

Formats the value using the given formatter.

impl<'a> Default for Function<'a>

fn default() -> Function<'a>

Returns the “default value” for a type.

impl<'a> Display for Function<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for Function<'a>

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<'a> Ord for Function<'a>

fn cmp(&self, other: &Function<'a>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<'a> PartialEq<Function<'a>> for Function<'a>

fn eq(&self, other: &Function<'a>) -> bool

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> PartialOrd<Function<'a>> for Function<'a>

fn partial_cmp(&self, other: &Function<'a>) -> 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.
