Struct Codec 

pub struct Codec {
    prefix: String,
    content_types: Vec<Box<str>>,
    default_ct: String,
    max_encoded_len: usize,
    max_decoded_body: usize,
    max_payload_bytes: usize,
}

Validated parcel codec; construct with Codec::new and reuse across calls.

Fields

prefix: String

content_types: Vec<Box<str>>

default_ct: String

max_encoded_len: usize

max_decoded_body: usize

max_payload_bytes: usize

Implementations

impl Codec

pub fn new(config: CodecConfig) -> Result<Self, CodecBuildError>

Validate config and produce a ready-to-use Codec.

Errors

Returns CodecBuildError when the prefix or content-type configuration is invalid.

pub fn prefix(&self) -> &str

The configured envelope prefix.

pub fn default_content_type(&self) -> &str

The default content type used when Codec::encode is called without an override.

pub fn encode( &self, payload: &[u8], content_type: Option<&str>, ) -> Result<String, ParcelError>

Encode payload into a parcel envelope (None content type uses the default).

Errors

Returns ParcelError for invalid input, compression failure, or an oversized envelope.

pub fn decode(&self, encoded: &str) -> Result<DecodedParcel, ParcelError>

Decode a parcel envelope into the recovered payload bytes plus metadata.

Errors

Returns ParcelError for an invalid envelope, checksum, body, or configured limit.

pub fn inspect(&self, encoded: &str) -> String

Decode encoded and render a multi-line human-readable summary (not a transport format).

fn parse<'a>( &self, encoded: &'a str, ) -> Result<(&'a str, &'a str, &'a str), ParcelError>

Trait Implementations

impl Clone for Codec

fn clone(&self) -> Codec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Codec

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

Formats the value using the given formatter.
