Trait mysql_common::misc::raw::bytes::BytesRepr

pub trait BytesRepr {
    type Ctx;

    const MAX_LEN: usize;
    const SIZE: Option<usize>;

    // Required methods
    fn serialize(text: &[u8], buf: &mut Vec<u8>);
    fn deserialize<'de>(
        ctx: Self::Ctx,
        buf: &mut ParseBuf<'de>
    ) -> Result<Cow<'de, [u8]>>;
}

Representation of a serialized bytes.

Required Associated Types

type Ctx

Required Associated Constants

const MAX_LEN: usize

Maximum length of bytes for this repr (depends on how lenght is stored).

const SIZE: Option<usize>

Required Methods

fn serialize(text: &[u8], buf: &mut Vec<u8>)

fn deserialize<'de>( ctx: Self::Ctx, buf: &mut ParseBuf<'de> ) -> Result<Cow<'de, [u8]>>

Implementation must check the length of the buffer if Self::SIZE.is_none().

Object Safety

This trait is not object safe.
