Struct Codec 

pub struct Codec { /* private fields */ }

JSONL conversation codec.

Use Codec::new() for plain JSONL. Pass a redact callback via Codec::with_redact to transform each message before encoding.

Implementations

impl Codec

pub fn new() -> Self

Plain JSONL codec, no redaction.

pub fn with_redact( redact: impl Fn(Value) -> Value + Send + Sync + 'static, ) -> Self

Codec that applies redact to each message before encoding.

pub fn save( &self, messages: &[Value], path: impl AsRef<Path>, ) -> Result<(), CodecError>

Write messages to a JSONL file. Creates parent dirs; overwrites.

pub fn append( &self, messages: &[Value], path: impl AsRef<Path>, ) -> Result<(), CodecError>

Append messages to an existing JSONL file (creates if absent).

pub fn load(&self, path: impl AsRef<Path>) -> Result<Vec<Value>, CodecError>

Load all messages from a JSONL file. Skips blank lines.

pub fn decode_line(line: &str) -> Result<Value, CodecError>

Decode a single JSONL line.

pub fn encode_line(&self, msg: Value) -> String

Encode a single message to a JSONL line (applies redact if set).
