Trait mysql_common::proto::MyDeserialize

pub trait MyDeserialize<'de>: Sized {
    type Ctx;

    const SIZE: Option<usize>;

    // Required method
    fn deserialize(ctx: Self::Ctx, buf: &mut ParseBuf<'de>) -> Result<Self>;
}

Deserialization for various MySql types.

Required Associated Types

type Ctx

Some structs defines deserialization in the context of another value.

Use () here if the deserialization procedure is defined without premises.

Required Associated Constants

const SIZE: Option<usize>

Size hint of a serialized value (in bytes), if it’s constant.

Required Methods

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

Deserializes self from the given buf.

Imlementation must consume corresponding amount of bytes from the buf.

Panic

Implementation must panic on insufficient buffer length if Self::SIZE.is_some(). One should use ParseBuf::checked_parse for checked deserialization.

Object Safety

This trait is not object safe.
