Struct SyncRuntimeConfig 

pub struct SyncRuntimeConfig<T = StoredConfig> { /* private fields */ }

Synchronous runtime configuration cache.

This type is intended for hot read paths where configuration is loaded from storage asynchronously at the boundary, but request handlers, middleware, policy builders, and task registries need cheap synchronous reads from an in-memory snapshot.

Implementations

impl<T> SyncRuntimeConfig<T>

where T: RuntimeConfigRecord,

pub fn new() -> Self

Creates an empty synchronous runtime cache.

pub fn replace(&self, configs: Vec<T>) -> Vec<RuntimeConfigChange<T>>

Replaces the snapshot from a full record list and returns the diff.

Restart-only rows keep their in-process record when the key already exists (value and flags stay until restart), mirroring Self::apply; the diff does not report those keys as changed. Removals are applied immediately, matching Self::remove.

pub fn snapshot(&self) -> SyncConfigSnapshot<T>

Returns a cloned snapshot for lock-free derived-state processing.

pub fn get_model(&self, key: &str) -> Option<T>

Returns the stored model for key.

pub fn get(&self, key: &str) -> Option<String>

Returns the storage string for key.

pub fn get_bool(&self, key: &str) -> Option<bool>

Parses a bool-like storage string for key.

pub fn get_i64(&self, key: &str) -> Option<i64>

Parses an i64 storage string for key.

pub fn get_u64(&self, key: &str) -> Option<u64>

Parses a u64 storage string for key.

pub fn get_string_or(&self, key: &str, default: &str) -> String

Returns a string value or default.

pub fn get_bool_or(&self, key: &str, default: bool) -> bool

Returns a bool value or default.

pub fn get_i64_or(&self, key: &str, default: i64) -> i64

Returns an i64 value or default.

pub fn get_u64_or(&self, key: &str, default: u64) -> u64

Returns a u64 value or default.

pub fn apply(&self, config: T) -> Option<RuntimeConfigChange<T>>

Applies one row to the snapshot.

If the incoming row requires restart and the key already exists, the update is ignored to preserve the in-process value until restart.

pub fn remove(&self, key: &str) -> Option<RuntimeConfigChange<T>>

Removes one key from the snapshot.
