Enum BlockEnd 

pub enum BlockEnd<'db> {
    NotSet,
    Return(Vec<VarUsage<'db>>, LocationId<'db>),
    Panic(VarUsage<'db>),
    Goto(BlockId, VarRemapping<'db>),
    Match {
        info: MatchInfo<'db>,
    },
}

Describes what happens to the program flow at the end of a Block.

Variants

NotSet

The block was created but still needs to be populated. Block must not be in this state in the end of the lowering phase.

Return(Vec<VarUsage<'db>>, LocationId<'db>)

This block ends with a return statement, exiting the function.

Panic(VarUsage<'db>)

This block ends with a panic.

Goto(BlockId, VarRemapping<'db>)

This block ends with a jump to a different block.

Match

Fields

info: MatchInfo<'db>

Trait Implementations

impl<'db> Clone for BlockEnd<'db>

fn clone(&self) -> BlockEnd<'db>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'db> Debug for BlockEnd<'db>

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

Formats the value using the given formatter.

impl<'db> DebugWithDb<'db> for BlockEnd<'db>

type Db = LoweredFormatter<'db>

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

fn debug<'me>(&'me self, db: &'db Self::Db) -> DebugWith<'me, 'db, Self::Db>

where Self: Sized + 'me,

fn into_debug<'me>(self, db: &'db Self::Db) -> DebugWith<'me, 'db, Self::Db>

where Self: Sized + 'me,

impl<'db> PartialEq for BlockEnd<'db>

fn eq(&self, other: &BlockEnd<'db>) -> 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.
