Trait CompressedData 

pub trait CompressedData<T, const MAX_UNCOMPRESSED_SIZE: u64, const COMPRESSION_LEVEL: i32>
where
    T: BorshSerialize + BorshDeserialize,
    Self: From<Box<[u8]>> + AsRef<Box<[u8]>>,
{
    // Provided methods
    fn from_boxed_slice(data: Box<[u8]>) -> Self { ... }
    fn encode(uncompressed: &T) -> Result<(Self, usize)> { ... }
    fn decode(&self) -> Result<(T, usize)> { ... }
    fn decode_with_limit(&self, limit: ByteSize) -> Result<(T, usize)> { ... }
    fn size_bytes(&self) -> usize { ... }
    fn as_slice(&self) -> &[u8]  { ... }
}

Helper trait for implementing a compressed structure for networking messages. The reason this is not a struct is because some derives do not work well on structs that have generics; e.g. ProtocolSchema.

Provided Methods

fn from_boxed_slice(data: Box<[u8]>) -> Self

Only use this if you are sure that the data is already encoded.

fn encode(uncompressed: &T) -> Result<(Self, usize)>

Borsh-serialize and compress the given data. Returns compressed data along with the raw (uncompressed) serialized data size.

fn decode(&self) -> Result<(T, usize)>

Decompress and borsh-deserialize the compressed data. Returns decompressed and deserialized data along with the raw (uncompressed) serialized data size.

fn decode_with_limit(&self, limit: ByteSize) -> Result<(T, usize)>

Decompress and borsh-deserialize the compressed data. Returns decompressed and deserialized data along with the raw (uncompressed) serialized data size.

fn size_bytes(&self) -> usize

fn as_slice(&self) -> &[u8]

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
