Struct RequestFilter 

pub struct RequestFilter { /* private fields */ }

A per-server request allowlist parsed from startup_params.

With no rules the filter is “pass-through”: every request is forwarded to the LLM (unchanged default behavior).

Implementations

impl RequestFilter

pub fn from_startup_params(params: Option<&Value>) -> Self

Parse a filter from a server’s startup_params.

Fail-open by design. A missing request_filter yields a pass-through filter, and any individual malformed rule (or invalid path regex) is skipped rather than failing the whole server. The consequence is worth stating plainly: if every rule you wrote is malformed, the filter ends up empty and every request reaches the LLM — slow and billable — instead of being rejected. Server startup is never failed on a bad filter, so the only signal is loud logging plus RequestFilter::warnings; callers are expected to forward those to the status channel.

pub fn default_response_parts( &self, ) -> Option<(u16, Vec<(String, String)>, String)>

The configured default_response as (status, headers, body), or None to keep the empty-200 default. Used by build_response when the model produced no send_http_response.

pub fn warnings(&self) -> &[String]

Problems found while parsing the filter config (empty when it is clean). Every one of these means the filter is doing less than the caller asked.

pub fn is_pass_through(&self) -> bool

True when no rules are configured — every request goes to the LLM.

pub fn allows(&self, req: &RequestData, path: &str) -> bool

Should this request be forwarded to the LLM?

pub fn rejection_parts(&self) -> (u16, Vec<(String, String)>, String)

The configured auto-response as raw parts, for transports that build their own response type (HTTP/2 through the h2 crate).

pub fn rejection(&self) -> Response<Full<Bytes>>

Build the auto-response for a request that matched no rule.

filtered_response comes straight from caller-supplied startup params, so this goes through the non-panicking builder.
