pub struct RpcHandler { /* private fields */ }Expand description
RPC request handler with intelligent caching capabilities
Handles incoming RPC requests by either serving from cache or forwarding to upstream RPC servers. Implements smart caching logic that avoids caching non-deterministic requests (e.g., “latest” block parameters).
Implementations§
Source§impl RpcHandler
impl RpcHandler
Sourcepub fn new(
provider_manager: Arc<ProviderManager>,
cache_manager: Arc<CacheManager>,
metrics_collector: Arc<MetricsCollector>,
) -> Result<Self>
pub fn new( provider_manager: Arc<ProviderManager>, cache_manager: Arc<CacheManager>, metrics_collector: Arc<MetricsCollector>, ) -> Result<Self>
Creates a new RPC handler with multiple providers and cache manager
§Arguments
provider_manager- Manager for multiple RPC providers with load balancingcache_manager- Shared cache manager for storing responsesmetrics_collector- Metrics collector for performance tracking
§Returns
A new RpcHandler instance ready to process requests
Sourcepub fn cache_manager(&self) -> &Arc<CacheManager>
pub fn cache_manager(&self) -> &Arc<CacheManager>
Sourcepub fn provider_manager(&self) -> &Arc<ProviderManager>
pub fn provider_manager(&self) -> &Arc<ProviderManager>
Returns a reference to the provider manager
Sourcepub fn metrics_collector(&self) -> &Arc<MetricsCollector>
pub fn metrics_collector(&self) -> &Arc<MetricsCollector>
Returns a reference to the metrics collector
Sourcepub async fn handle_request(&self, request: Value) -> Result<Value>
pub async fn handle_request(&self, request: Value) -> Result<Value>
Handles an RPC request with intelligent caching
Determines whether to serve from cache or forward to upstream based on:
- Whether the method is cacheable (see CACHEABLE_METHODS)
- Whether the request contains non-deterministic block parameters
- Whether a cached response already exists
- Whether the response is valid (for debug/trace methods)
§Arguments
request- The JSON-RPC request to handle
§Returns
The JSON-RPC response, either from cache or upstream
Sourcepub fn generate_cache_key(&self, request: &Value) -> String
pub fn generate_cache_key(&self, request: &Value) -> String
Generate a unique cache key for the given RPC request based on method and parameters

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().

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.
fn clear(&self) -> Painted<&T>
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);Source§impl<T> Pipe for Twhere
