pub struct LoroStore { /* private fields */ }Expand description
Server-side per-row LoroDoc cache + persistence layer.
One instance per Runtime. Cheap to clone via Arc; internally
guards a HashMap of doc handles, each itself behind a Mutex so
concurrent access to different rows doesn’t contend.
Implementations§
Source§impl LoroStore
impl LoroStore
pub fn new() -> Self
Sourcepub fn apply_patch(
&self,
conn: &Connection,
entity: &str,
row_id: &str,
fields: &[CrdtField],
patch: &Value,
) -> Result<Value, LoroStoreError>
pub fn apply_patch( &self, conn: &Connection, entity: &str, row_id: &str, fields: &[CrdtField], patch: &Value, ) -> Result<Value, LoroStoreError>
Apply a JSON {field: value} patch to the row’s doc, persist the
new snapshot, and return the projected JSON (the row shape SQLite
stores in the materialized view).
Sourcepub fn apply_remote_update(
&self,
conn: &Connection,
entity: &str,
row_id: &str,
fields: &[CrdtField],
update: &[u8],
) -> Result<Value, LoroStoreError>
pub fn apply_remote_update( &self, conn: &Connection, entity: &str, row_id: &str, fields: &[CrdtField], update: &[u8], ) -> Result<Value, LoroStoreError>
Apply a binary update from a peer (typed-protocol client push or server-to-server replication). Persists the new snapshot. Returns the projected JSON for SQLite materialization so the materialized view stays in sync with the CRDT after remote-driven changes.
Sourcepub fn snapshot(
&self,
conn: &Connection,
entity: &str,
row_id: &str,
) -> Result<Vec<u8>, LoroStoreError>
pub fn snapshot( &self, conn: &Connection, entity: &str, row_id: &str, ) -> Result<Vec<u8>, LoroStoreError>
Get the full snapshot for a row. Sent to a fresh client when it
subscribes. Returns an empty Vec for rows that don’t exist yet.
Sourcepub fn update_since(
&self,
conn: &Connection,
entity: &str,
row_id: &str,
since: &VersionVector,
) -> Result<Vec<u8>, LoroStoreError>
pub fn update_since( &self, conn: &Connection, entity: &str, row_id: &str, since: &VersionVector, ) -> Result<Vec<u8>, LoroStoreError>
Get an incremental update since since — only the ops the peer
hasn’t seen. Used to catch up a peer that’s been disconnected.
Sourcepub fn evict(&self, entity: &str, row_id: &str)
pub fn evict(&self, entity: &str, row_id: &str)
Drop a row’s doc from the in-memory cache. Useful for tests and for the eventual eviction policy. Doesn’t touch the sidecar; the next read will re-hydrate from disk.
Sourcepub fn cached_rows(&self) -> usize
pub fn cached_rows(&self) -> usize
Number of rows currently held in memory. Diagnostic.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().

fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.

renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
