Module structured_output 

Tokenizer-aware hard constraints for structured output.

A factory owns the tokenizer trie and grammar compiler and is shared by an engine. Each request gets an independent matcher with no shared mutable grammar state.

Structs

StructuredOutputBudgetPlan

Immutable per-request output budget used when a structured grammar starts after a reasoning delimiter.

StructuredOutputFactory

Shared, immutable tokenizer and grammar compilation state.

StructuredOutputMaskOutcome

Allocation-free hot-path result of one structured-output mask operation.

StructuredOutputProcessor

Per-request structured-output parser state.

StructuredOutputProgress

Terminal/debug snapshot that distinguishes activation failures from an incomplete grammar without retaining generated text.

Enums

StructuredOutputPhase

Typed phase returned after applying a structured-output constraint.

StructuredOutputTokenClass

Privacy-safe lexical class for the tail of an incomplete grammar.
