Trait ComplexType

pub trait ComplexType {
    const IS_ARRAY: bool;

    // Required methods
    fn header_size<T>(element_count: u32) -> usize
       where T: StorageFormat;
    fn value_entry_offset<T>(element_count: u32, pos: u32) -> usize
       where T: StorageFormat;
}

Type of a complex jsonb value (array or object).

Required Associated Constants

const IS_ARRAY: bool

Required Methods

fn header_size<T>(element_count: u32) -> usize

where T: StorageFormat,

Calculates header size for this type.

fn value_entry_offset<T>(element_count: u32, pos: u32) -> usize

where T: StorageFormat,

Calculates an offset to the given value entry.

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 ComplexType for Array

const IS_ARRAY: bool = true

impl ComplexType for Object

const IS_ARRAY: bool = false
