Struct ModelChatTemplate 

pub struct ModelChatTemplate {
    pub template: String,
    pub source: String,
    pub bos_token: Option<String>,
    pub eos_token: Option<String>,
    pub tool_call_protocol: ApiToolCallProtocol,
    pub output_protocol: ModelOutputProtocol,
    pub reasoning_protocol: ModelReasoningProtocol,
    pub reasoning_default_enabled: bool,
    pub reasoning_effort_support: ReasoningEffortSupport,
}

Model-provided chat template, usually from GGUF or Hugging Face metadata.

Fields

template: String

source: String

bos_token: Option<String>

eos_token: Option<String>

tool_call_protocol: ApiToolCallProtocol

output_protocol: ModelOutputProtocol

reasoning_protocol: ModelReasoningProtocol

reasoning_default_enabled: bool

reasoning_effort_support: ReasoningEffortSupport

Declared by the model implementation, independently of output parsing.

Implementations

impl ModelChatTemplate

pub fn new(template: impl Into<String>, source: impl Into<String>) -> Self

pub fn reasoning_enabled(&self, requested: Option<bool>) -> bool

pub fn reasoning_capability(&self) -> ModelReasoningProtocol

The full output capability, including Harmony’s separate message parser. This observation does not change template rendering or reasoning defaults.

pub fn supports_thinking_control(&self) -> bool

Observe an actual template switch. Reasoning output alone does not prove that enable_thinking can disable it (an always-open template cannot).

pub fn set_output_protocol(&mut self, protocol: ModelOutputProtocol)

Bind the resolved model capability after loading its unchanged template bytes, then probe reasoning with that protocol’s actual delimiters.

pub fn validate_reasoning_effort(&self, effort: ReasoningEffort) -> Result<()>

Trait Implementations

impl Clone for ModelChatTemplate

fn clone(&self) -> ModelChatTemplate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModelChatTemplate

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

Formats the value using the given formatter.
