Struct SimpleStreamOptionsPatch 

pub struct SimpleStreamOptionsPatch {
    pub timeout: Option<Option<Duration>>,
    pub max_retries: Option<Option<u32>>,
    pub max_retry_delay: Option<Option<Duration>>,
    pub headers: Option<BTreeMap<String, Option<String>>>,
    pub metadata: Option<BTreeMap<String, Option<String>>>,
    pub cache_retention: Option<Option<CacheRetention>>,
    pub max_tokens: Option<Option<u64>>,
    pub temperature: Option<Option<f64>>,
    pub session_id: Option<Option<String>>,
}

A patch against SimpleStreamOptions returned by ProviderHooks::before_request. Mirrors TS beforeRequest’s per-request overrides but targets the live SimpleStreamOptions (the type stream_simple receives), not the harness pinned subset. Option<Option<T>> semantics: outer None = “leave this field”; inner Some(None) on the headers/metadata maps = “delete this key”.

This is distinct from the harness-side AgentHarnessStreamOptionsPatch (which lives in rpi-harness and patches AgentHarnessStreamOptions). Both exist; this one is the rpi-ai seam so provider hooks can be defined without a rpi-harness cycle.

Fields

timeout: Option<Option<Duration>>

max_retries: Option<Option<u32>>

max_retry_delay: Option<Option<Duration>>

headers: Option<BTreeMap<String, Option<String>>>

None = leave; Some(map) = merge, inner None deletes a key.

metadata: Option<BTreeMap<String, Option<String>>>

None = leave; Some(map) = merge, inner None deletes a key.

cache_retention: Option<Option<CacheRetention>>

max_tokens: Option<Option<u64>>

temperature: Option<Option<f64>>

session_id: Option<Option<String>>

Implementations

impl SimpleStreamOptionsPatch

pub fn apply(&self, opts: &mut SimpleStreamOptions)

Apply this patch to opts in place. Mirrors the harness patch semantics: outer None = leave the field; an explicit value replaces it; None inside a map entry deletes that key.

Trait Implementations

impl Clone for SimpleStreamOptionsPatch

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SimpleStreamOptionsPatch

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

Formats the value using the given formatter.

impl Default for SimpleStreamOptionsPatch

fn default() -> Self

Returns the “default value” for a type.
