Struct Footprint

pub struct Footprint {
    pub count: u64,
    pub size: u64,
}

The resource footprint of a bunch of blobs. We assume only the number of blobs and their total size in bytes matter.

Fields

count: u64

The number of blobs.

size: u64

The total size of the blobs in bytes.

Implementations

impl Footprint

pub fn from_parts(items: usize, len: usize) -> Self

Construct a footprint directly from items and len.

pub fn from_encodable(e: impl Encode) -> Self

Construct a footprint with one item, and size equal to the encoded size of e.

pub fn from_mel<E: MaxEncodedLen>() -> Self

Construct a footprint with one item, and size equal to the max encoded length of E.

Trait Implementations

impl Clone for Footprint

fn clone(&self) -> Footprint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Price, Balance> Convert<Footprint, Balance> for ConstantStoragePrice<Price, Balance>

where Price: Get<Balance>, Balance: From<u64> + Saturating,

fn convert(_: Footprint) -> Balance

Make conversion.

impl<Base, Slope, Balance> Convert<Footprint, Balance> for LinearStoragePrice<Base, Slope, Balance>

where Base: Get<Balance>, Slope: Get<Balance>, Balance: From<u64> + Saturating,

fn convert(a: Footprint) -> Balance

Make conversion.

impl Debug for Footprint

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

Formats the value using the given formatter.

impl Default for Footprint

fn default() -> Footprint

Returns the “default value” for a type.

impl PartialEq for Footprint

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

Tests for self and other values to be equal, and is used by ==.

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

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