Info about primary key with a prefix (see PrimaryKeysWithPrefix).

Implementations

impl PrimaryKeyWithPrefix

pub fn new(column_index: u64, prefix_length: u64) -> Self

Creates a new PK with prefix.

pub fn column_index(&self) -> u64

Returns the column index

pub fn prefix_length(&self) -> u64

Returns the prefix length. 0 means that the whole column value is used.

type Ctx = ()

Some structs defines deserialization in the context of another value.

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

Deserializes self from the given buf.

impl MySerialize for PrimaryKeyWithPrefix

fn serialize(&self, buf: &mut Vec<u8>)
