Struct salsa_2022::event::Event

pub struct Event {
    pub runtime_id: RuntimeId,
    pub kind: EventKind,
}

The Event struct identifies various notable things that can occur during salsa execution. Instances of this struct are given to salsa_event.

Fields

runtime_id: RuntimeId

The id of the snapshot that triggered the event. Usually 1-to-1 with a thread, as well.

kind: EventKind

What sort of event was it.

Trait Implementations

impl Debug for Event

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

Formats the value using the given formatter.

impl<Db> DebugWithDb<Db> for Eventwhere
    Db: ?Sized + Database,

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

if include_all_fields is false only identity fields should be read, which means: - for #[salsa::input] no fields - for #[salsa::tracked] only fields with #[id] attribute - for #[salsa::interned] any field

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

fn debug_with<'me, 'db>(
    &'me self,
    db: &'me Db,
    include_all_fields: bool
) -> DebugWith<'me, Db>where
    Self: Sized + 'me,

fn debug_all<'me, 'db>(&'me self, db: &'me Db) -> DebugWith<'me, Db>where
    Self: Sized + 'me,

Be careful when using this method inside a tracked function, because the default macro generated implementation will read all fields, maybe introducing undesired dependencies.

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

fn into_debug_all<'me, 'db>(self, db: &'me Db) -> DebugWith<'me, Db>where
    Self: Sized + 'me,

Be careful when using this method inside a tracked function, because the default macro generated implementation will read all fields, maybe introducing undesired dependencies.
