Enum CachePolicy 

pub enum CachePolicy {
    Enabled {
        ttl: Duration,
    },
    Disabled,
}

Cache policy for language plugins.

Plugins can opt out of caching or specify custom TTL (time-to-live) values.

Default Policy

By default, all plugins use CachePolicy::Enabled with a 1-hour TTL.

Examples

use sqry_core::cache::CachePolicy;
use sqry_core::plugin::LanguagePlugin;
use std::time::Duration;

impl LanguagePlugin for RustPlugin {
    fn cache_policy(&self) -> CachePolicy {
        // Stable grammar - long TTL
        CachePolicy::Enabled {
            ttl: Duration::from_secs(3600) // 1 hour
        }
    }
}

impl LanguagePlugin for ExperimentalPlugin {
    fn cache_policy(&self) -> CachePolicy {
        // Experimental - disable caching
        CachePolicy::Disabled
    }
}

Variants

Enabled

Caching enabled with the specified time-to-live.

Cache entries expire after the TTL and will be reparsed on next access.

Fields

ttl: Duration

Time-to-live for cache entries.

Disabled

Caching disabled for this plugin.

All queries will trigger fresh parsing, bypassing the cache entirely.

Implementations

impl CachePolicy

pub const DEFAULT_TTL: Duration

Default TTL for enabled caching (1 hour).

pub fn default_enabled() -> Self

Create an enabled policy with the default TTL.

Examples

use sqry_core::cache::CachePolicy;

let policy = CachePolicy::default_enabled();

pub fn enabled(ttl: Duration) -> Self

Create an enabled policy with a custom TTL.

Examples

use sqry_core::cache::CachePolicy;
use std::time::Duration;

let policy = CachePolicy::enabled(Duration::from_secs(7200)); // 2 hours

pub fn disabled() -> Self

Create a disabled policy.

Examples

use sqry_core::cache::CachePolicy;

let policy = CachePolicy::disabled();

pub fn is_enabled(&self) -> bool

Check if caching is enabled.

pub fn ttl(&self) -> Option<Duration>

Get the TTL if caching is enabled.

Trait Implementations

impl Clone for CachePolicy

fn clone(&self) -> CachePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CachePolicy

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

Formats the value using the given formatter.

impl Default for CachePolicy

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for CachePolicy

fn eq(&self, other: &CachePolicy) -> 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.
