Struct Bitcode 

pub struct Bitcode<T: ?Sized>(pub T);

A wrapper type for bitcode-serialized data in SQL databases.

Bitcode<T> wraps a value of type T and provides automatic serialization/deserialization using the bitcode binary format when storing to or reading from SQL databases.

Features

• Compact binary format - Efficient storage compared to JSON or other text formats
• Type-safe - Compile-time checking of serialization capabilities
• Fast - High performance serialization and deserialization

Database Support

Currently implements SQLx traits for SQLite. Data is stored as BLOB.

Example

use evento_sql::sql_types::Bitcode;
use bitcode::{Encode, Decode};

#[derive(Encode, Decode)]
struct MyData {
    value: i32,
    name: String,
}

// Wrap data for storage
let data = Bitcode(MyData { value: 42, name: "test".into() });

// Encode to bytes
let bytes = data.encode_to()?;

// Decode from bytes
let decoded = Bitcode::<MyData>::decode_from_bytes(&bytes)?;
assert_eq!(decoded.value, 42);

Deref

Bitcode<T> implements Deref and DerefMut to T, allowing transparent access to the inner value.

Tuple Fields

0: T

Implementations

impl<T> Bitcode<T>

where T: Encode,

pub fn encode_to(&self) -> Vec<u8>

Serializes the wrapped value to a byte vector using bitcode.

impl<T> Bitcode<T>

where T: DecodeOwned,

pub fn decode_from_bytes(bytes: &[u8]) -> Result<Self, Error>

Deserializes a value from a byte slice using bitcode.

Errors

Returns an error if deserialization fails or the data is invalid.

Writes the value of self into buf without moving self.

fn encode( self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, Box<dyn Error + Send + Sync>>

Writes the value of self into buf in the expected format for the database.

fn produces(&self) -> Option<<DB as Database>::TypeInfo>

fn size_hint(&self) -> usize

impl<T> From<T> for Bitcode<T>

fn from(value: T) -> Self

Converts to this type from the input type.
