Trait StorageFormat

pub trait StorageFormat {
    const IS_LARGE: bool;
    const OFFSET_SIZE: u8;
    const KEY_ENTRY_SIZE: u8 = _;
    const VALUE_ENTRY_SIZE: u8 = _;

    // Required method
    fn eat_offset(buf: &mut ParseBuf<'_>) -> u32;
}

JSONB storage format for objects and arrays. See ComplexType.

Required Associated Constants

const IS_LARGE: bool

const OFFSET_SIZE: u8

The size of offset or size fields.

Provided Associated Constants

const KEY_ENTRY_SIZE: u8 = _

const VALUE_ENTRY_SIZE: u8 = _

Required Methods

fn eat_offset(buf: &mut ParseBuf<'_>) -> u32

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.

Implementors

impl StorageFormat for Large

const IS_LARGE: bool = true

const OFFSET_SIZE: u8 = 4u8

impl StorageFormat for Small
