Enum GrammarSource 

pub enum GrammarSource {
    None,
    User,
    OutputFormat,
    ToolCalls,
}

How a grammar was obtained, which decides whether the generation prompt is prefilled into it.

Getting this wrong is silent: prefilling a user grammar consumes tokens it never expected, and not prefilling a tool-call grammar forces the model to re-emit the generation prompt.

Variants

None

No grammar.

User

Supplied verbatim by the caller. Never prefilled.

OutputFormat

Generated from a JSON schema. Prefilled.

ToolCalls

Generated by a chat template for tool calling. Prefilled.
