Struct DatabaseImpl 

pub struct DatabaseImpl { /* private fields */ }

Default database implementation that you can use if you don’t require any custom user data.

Implementations

impl DatabaseImpl

pub fn new() -> Self

Create a new database; equivalent to Self::default.

pub fn storage(&self) -> &Storage<Self>

Trait Implementations

impl Clone for DatabaseImpl

fn clone(&self) -> DatabaseImpl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Database for DatabaseImpl

fn trigger_lru_eviction(&mut self)

Enforces current LRU limits, evicting entries if necessary.

fn synthetic_write(&mut self, durability: Durability)

A “synthetic write” causes the system to act as though some input of durability durability has changed, triggering a new revision. This is mostly useful for profiling scenarios.

fn trigger_cancellation(&mut self)

This method triggers cancellation. If you invoke it while a snapshot exists, it will block until that snapshot is dropped – if that snapshot is owned by the current thread, this could trigger deadlock.

fn report_untracked_read(&self)

Reports that the query depends on some state unknown to salsa.

fn ingredient_debug_name( &self, ingredient_index: IngredientIndex, ) -> Cow<'_, str>

Return the “debug name” (i.e., the struct name, etc) for an “ingredient”, which are the fine-grained components we use to track data. This is intended for debugging and the contents of the returned string are not semver-guaranteed.

fn unwind_if_revision_cancelled(&self)

Starts unwinding the stack if the current revision is cancelled.

fn attach<R>(&self, op: impl FnOnce(&Self) -> R) -> R

where Self: Sized,

Execute op with the database in thread-local storage for debug print-outs.

impl Default for DatabaseImpl

fn default() -> Self

Returns the “default value” for a type.
