Struct BatchEncoder 

pub struct BatchEncoder { /* private fields */ }

Reusable encoder. Once capacities are warmed, clear and finish allocate no memory.

Implementations

impl BatchEncoder

pub fn with_capacity( record_bytes: usize, string_bytes: usize, string_count: usize, ) -> Self

pub fn clear(&mut self)

pub fn encode(&mut self, mutation: &Mutation<'_>) -> Result<(), ProtocolError>

pub fn finish(&mut self) -> Result<&[u8], ProtocolError>

pub fn arena(&self) -> (*const u8, usize)

Where the arena a finished batch lives in starts, and how much of it is mapped.

A runtime that cannot read the Host’s memory directly wraps this range once and keeps the view: every batch is a prefix of the arena, so it is read where it lies and no byte is copied out. Growing the arena moves it, which is why the address is reported again on every call rather than once at startup.

pub fn capacity(&self) -> usize

Trait Implementations

impl Default for BatchEncoder

fn default() -> Self

Returns the “default value” for a type.
