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 = Location { block: START_BLOCK, statement_index: 0 }

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
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl<'__ctx> HashStable<StableHashingContext<'__ctx>> for Location

fn hash_stable(
    &self,
    __hcx: &mut StableHashingContext<'__ctx>,
    __hasher: &mut StableHasher
)

impl Ord for Location

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

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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
