Struct scale_bits::scale::format::Format

pub struct Format {
    pub store: StoreFormat,
    pub order: OrderFormat,
}

A description of the format used to SCALE encode some bits.

Fields

store: StoreFormat

The StoreFormat defines the size of each chunk that’s written (eg u8, u16 etc).

order: OrderFormat

The OrderFormat determines the order in which we write bits to the store type; do we write to the least significant bit first and work up, or write to the most significant byte first and work down.

Implementations

impl Format

pub fn new(store: StoreFormat, order: OrderFormat) -> Self

Define a new format by providing a store and order.

Example

use scale_bits::scale::format::{ Format, StoreFormat, OrderFormat };

let format = Format::new(StoreFormat::U8, OrderFormat::Lsb0);

pub fn from_metadata( ty: &TypeDefBitSequence<PortableForm>, types: &PortableRegistry ) -> Result<Format, FromMetadataError>

Use metadata to obtain details about the format.

Trait Implementations

impl Clone for Format

fn clone(&self) -> Format

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Format

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<Format> for Format

fn eq(&self, other: &Format) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
