Struct DatabaseOptions 

pub struct DatabaseOptions {
    pub parse_lru: usize,
    pub sema_lru: usize,
    pub plan_lru: usize,
    pub formatted_lru: usize,
}

Per-query LRU capacity configuration for crate::workspace::Database.

Pass to crate::workspace::Database::with_options at construction. The options are immutable after construction — Salsa does not support changing LRU capacity mid-session.

Example

use cyrs_db::{Database, DatabaseOptions};

let opts = DatabaseOptions { parse_lru: 512, ..DatabaseOptions::default() };
let db = Database::with_options(opts);

Fields

parse_lru: usize

Maximum number of memoised parse_cst / HIR results.

Covers the parse_cst tracked function. Default: 256.

sema_lru: usize

Maximum number of memoised semantic-analysis results.

Covers resolved_names and sema_diagnostics. Default: 256.

plan_lru: usize

Maximum number of memoised logical-plan results.

Covers plan_of. Default: 256.

formatted_lru: usize

Maximum number of memoised formatted-output results.

Covers any future formatted tracked query. Default: 256. Currently unused — reserved for the formatter tracked query (bead cy-31b-followup).

Trait Implementations

impl Clone for DatabaseOptions

fn clone(&self) -> DatabaseOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DatabaseOptions

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

Formats the value using the given formatter.

impl Default for DatabaseOptions

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DatabaseOptions

fn eq(&self, other: &DatabaseOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
