Enum DefLocation 

pub enum DefLocation {
    Statement(StatementLocation),
    BlockEntry(BlockId),
}

Where a variable is defined.

Variants

Statement(StatementLocation)

Defined by a statement at the given location.

BlockEntry(BlockId)

Defined at block entry (parameter, goto remapping, or match arm binding).

Implementations

impl DefLocation

pub fn block(&self) -> BlockId

Returns the BlockId of the block in which the variable is defined.

Trait Implementations

impl Clone for DefLocation

fn clone(&self) -> DefLocation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DefLocation

impl Debug for DefLocation

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

Formats the value using the given formatter.

impl Eq for DefLocation

impl Hash for DefLocation

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 PartialEq for DefLocation

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

Tests for self and other values to be equal, and is used by ==.

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

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