Struct Weight 

pub struct Weight(/* private fields */);

Weight in weight units (WU). Max block weight is 4,000,000 WU.

Implementations

impl Weight

pub const MAX_BLOCK: Weight

Maximum block weight in Bitcoin (4 million weight units). Note: Pre-SegWit 1MB blocks have weight = size * 4 = 4M, so this is consistent across all blocks.

pub fn from_sizes(base_size: u32, total_size: u32) -> Weight

Compute weight from base size and total size. Formula: weight = base_size * 3 + total_size (since total_size = base_size + witness_size, this equals base_size * 4 + witness_size)

pub fn to_vbytes_ceil(&self) -> u64

pub fn to_vbytes_floor(&self) -> u64

pub fn fullness(&self) -> f32

Returns block fullness as a ratio (0–1+) relative to MAX_BLOCK.

Methods from Deref<Target = u64>

pub const MIN: u64 = 0

pub const MAX: u64

pub const BITS: u32

Trait Implementations

impl Add for Weight

type Output = Weight

The resulting type after applying the + operator.

fn add(self, rhs: Weight) -> <Weight as Add>::Output

Performs the + operation.

impl AddAssign for Weight

fn add_assign(&mut self, rhs: Weight)

Performs the += operation.

impl Bytes for Weight

type Array = <u64 as Bytes>::Array

The byte array type returned by to_bytes. For fixed-size types, this is [u8; N] where N is the size of the type.

fn to_bytes(&self) -> <Weight as Bytes>::Array

Serializes this value to bytes.

fn from_bytes(bytes: &[u8]) -> Result<Weight, Error>

Deserializes a value from bytes.

const IS_NATIVE_LAYOUT: bool = false

Whether the byte representation from to_bytes is identical to the in-memory representation of Self. When true, bulk operations can use memcpy instead of per-element deserialization.

impl CheckedSub for Weight

fn checked_sub(self, rhs: Weight) -> Option<Weight>

impl Clone for Weight

fn clone(&self) -> Weight

Returns a duplicate of the value.

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

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

Formats the value using the given formatter.

impl Default for Weight

fn default() -> Weight

Returns the “default value” for a type.

impl Deref for Weight

type Target = u64

Write in CSV format. Override for types needing CSV escaping (e.g., quoting commas).

impl JsonSchema for Weight

fn schema_name() -> Cow<'static, str>

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Ord for Weight

fn cmp(&self, other: &Weight) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

impl PartialEq for Weight

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

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

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