Trait MyDeserialize

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

Expand description

Deserialization for various MySql types.

Required Associated Constants§

const SIZE: Option<usize>

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

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 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.

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.
