Enum ExceptionTableItem

pub enum ExceptionTableItem {
    Tag(ExceptionTag, BlockCall),
    Default(BlockCall),
    Context(Value),
}

A single item in the match-list of an exception table.

Variants

Tag(ExceptionTag, BlockCall)

A tag match, taking the specified block-call destination if the tag matches the one in the thrown exception. (The match predicate is up to the runtime; Cranelift only emits metadata containing this tag.)

Default(BlockCall)

A default match, always taking the specified block-call destination.

Context(Value)

A dynamic context update, applying to all tags until the next update. (Cranelift does not interpret this context, but only provides information to the runtime regarding where to find it.)
