Struct SchemaState 

pub struct SchemaState {
    pub is_complete: bool,
    /* private fields */
}

State machine that tracks JSON generation progress against a schema.

Characters are fed one at a time; the machine maintains a stack of context frames mirroring the nesting structure of the JSON being generated.

Fields

is_complete: bool

Whether we’ve completed the root value.

Implementations

impl SchemaState

pub fn new(schema: &SchemaType) -> Self

Create a new state machine rooted at the given schema.

pub fn feed_char(&mut self, ch: char) -> Result<bool, SchemaError>

Feed a character and check if it’s valid according to the schema.

Returns Ok(true) if the character was accepted, Ok(false) if it was rejected but didn’t violate hard constraints, or Err on a definite schema violation.

pub fn valid_next_chars(&self) -> Vec<char>

Get the set of valid next characters at the current position.

This is a simplified heuristic — for complex schemas, the set may be conservative (allowing more than strictly valid).

pub fn continuation_pattern(&self) -> String

Get a regex pattern for valid continuations (for masking logits).

pub fn buffer(&self) -> &str

Returns a reference to the characters generated so far.

pub fn depth(&self) -> usize

Returns the current nesting depth (number of frames on the stack).

Trait Implementations

impl Clone for SchemaState

fn clone(&self) -> SchemaState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaState

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

Formats the value using the given formatter.
