Struct Encoder

pub struct Encoder { /* private fields */ }

Encoder for converting metrics from a registry into serializable updates.

Tracks schema changes and generates Update objects that can be transmitted to a Decoder.

Implementations

impl Encoder

pub fn new(registry: RwLockRegistry) -> Self

Creates a new encoder for the given registry.

The encoder will track schema changes and only include schema information in updates when it has changed.

pub fn new_with_opts(registry: RwLockRegistry, opts: EncoderOpts) -> Self

Creates a new encoder for the given registry with custom options.

pub fn export(&mut self) -> Update

Exports the current state of the registry as an update.

Returns an Update containing the current metric values and optionally the schema (if it has changed since the last export).

pub fn export_bytes(&mut self) -> Result<Vec<u8>, Error>

Exports the current state of the registry as serialized bytes.

Returns the serialized bytes of an Update using postcard encoding.

Trait Implementations

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

Formats the value using the given formatter.
