Struct rustc_middle::mir::Location

pub struct Location {
    pub block: BasicBlock,
    pub statement_index: usize,
}

Location represents the position of the start of the statement; or, if statement_index equals the number of statements, then the start of the terminator.

Fields

block: BasicBlock

The block that the location is within.

statement_index: usize

Implementations

impl Location

pub const START: Location

pub fn successor_within_block(&self) -> Location

Returns the location immediately after this one within the enclosing block.

Note that if this location represents a terminator, then the resulting location would be out of bounds and invalid.

pub fn is_predecessor_of<'tcx>(
    &self,
    other: Location,
    body: &Body<'tcx>
) -> bool

Returns true if other is earlier in the control flow graph than self.

pub fn dominates(
    &self,
    other: Location,
    dominators: &Dominators<BasicBlock>
) -> bool

Trait Implementations

impl Clone for Location

fn clone(&self) -> Location

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Location

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

Formats the value using the given formatter.

impl Hash for Location

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

impl Ord for Location

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

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

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

impl PartialEq<Location> for Location

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

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

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

This method tests for !=.

impl PartialOrd<Location> for Location

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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