Struct LocalBindingTimeline 

pub struct LocalBindingTimeline { /* private fields */ }

When each local name of one callable is in effect.

entry_bindings are bound over the whole callable (parameters, numbered block parameters, inherited captures). activations map an assigned name to the earliest byte offset of an assignment target with that name; the name reads as a local at any byte at or after that offset.

Implementations

impl LocalBindingTimeline

pub fn is_active_at(&self, name: &str, source_byte: usize) -> bool

pub fn activations(&self) -> impl Iterator<Item = (&str, usize)>

Every assignment-activated name with the byte offset at which it becomes active, in unspecified order.

pub fn active_names_at(&self, source_byte: usize) -> Vec<&str>
