Struct CallSettings 

pub struct CallSettings {
    pub max_output_tokens: Option<u32>,
    pub temperature: Option<f64>,
    pub top_p: Option<f64>,
    pub top_k: Option<u32>,
    pub presence_penalty: Option<f64>,
    pub frequency_penalty: Option<f64>,
    pub stop_sequences: Option<Vec<String>>,
    pub seed: Option<u64>,
    pub reasoning: ReasoningEffort,
    pub headers: Headers,
    pub provider_options: ProviderOptions,
}

Sampling and request settings applied to every model call.

Rust types absorb most validation (u32, f64, Vec<String>); the remaining runtime checks are max_output_tokens >= 1 and finite floats.

Fields

max_output_tokens: Option<u32>

Maximum number of output tokens.

temperature: Option<f64>

Sampling temperature.

top_p: Option<f64>

Nucleus sampling.

top_k: Option<u32>

Top-k sampling.

presence_penalty: Option<f64>

Presence penalty.

frequency_penalty: Option<f64>

Frequency penalty.

stop_sequences: Option<Vec<String>>

Stop sequences.

seed: Option<u64>

Random seed.

reasoning: ReasoningEffort

Reasoning effort.

headers: Headers

Extra request headers.

provider_options: ProviderOptions

Provider-specific options.

Implementations

impl CallSettings

pub fn validate(&self) -> Result<(), Error>

Checks the runtime invariants.

Errors

Returns Error::InvalidArgument naming the offending setting.

pub fn apply(&self, options: &mut CallOptions)

Copies the settings into options, merging headers and provider options.

pub fn merge(&mut self, other: &CallSettings)

Overlays the set fields of other onto self (used by prepare_step and default-settings middleware).

Trait Implementations

impl Clone for CallSettings

fn clone(&self) -> CallSettings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CallSettings

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

Formats the value using the given formatter.

impl Default for CallSettings

fn default() -> CallSettings

Returns the “default value” for a type.

impl PartialEq for CallSettings

fn eq(&self, other: &CallSettings) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
