Struct bdk_chain::bitcoin::blockdata::Weight

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

Represents block weight - the weight of a transaction or block.

This is an integer newtype representing weigth in wu. It provides protection against mixing up the types as well as basic formatting features.

Implementations§

§

impl Weight

pub const ZERO: Weight = _

0 wu.

Equivalent to MIN, may better express intent in some contexts.

pub const MIN: Weight = _

Minimum possible value (0 wu).

Equivalent to ZERO, may better express intent in some contexts.

pub const MAX: Weight = _

Maximum possible value.

pub const WITNESS_SCALE_FACTOR: u64 = 4u64

The factor that non-witness serialization data is multiplied by during weight calculation.

pub const MAX_BLOCK: Weight = _

The maximum allowed weight for a block, see BIP 141 (network rule).

pub const MIN_TRANSACTION: Weight = _

The minimum transaction weight for a valid serialized transaction.

pub const fn from_wu(wu: u64) -> Weight

Directly constructs Weight from weight units.

pub const fn from_wu_usize(wu: usize) -> Weight

Directly constructs Weight from usize weight units.

pub fn from_kwu(wu: u64) -> Option<Weight>

Constructs Weight from kilo weight units returning None if an overflow occurred.

pub fn from_vb(vb: u64) -> Option<Weight>

Constructs Weight from virtual bytes, returning None on overflow.

pub const fn from_vb_unwrap(vb: u64) -> Weight

Constructs Weight from virtual bytes panicking on overflow.

§Panics

If the conversion from virtual bytes overflows.

pub const fn from_vb_unchecked(vb: u64) -> Weight

Constructs Weight from virtual bytes without an overflow check.

pub const fn from_witness_data_size(witness_size: u64) -> Weight

Constructs Weight from witness size.

pub const fn from_non_witness_data_size(non_witness_size: u64) -> Weight

Constructs Weight from non-witness size.

pub const fn to_wu(self) -> u64

Returns raw weight units.

Can be used instead of into() to avoid inference issues.

pub const fn to_kwu_floor(self) -> u64

Converts to kilo weight units rounding down.

pub const fn to_vbytes_floor(self) -> u64

Converts to vB rounding down.

pub const fn to_vbytes_ceil(self) -> u64

Converts to vB rounding up.

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

Checked addition.

Computes self + rhs returning None if an overflow occurred.

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

Checked subtraction.

Computes self - rhs returning None if an overflow occurred.

pub fn checked_mul(self, rhs: u64) -> Option<Weight>

Checked multiplication.

Computes self * rhs returning None if an overflow occurred.

pub fn checked_div(self, rhs: u64) -> Option<Weight>

Checked division.

Computes self / rhs returning None if rhs == 0.

pub fn scale_by_witness_factor(self) -> Option<Weight>

Scale by witness factor.

Computes self * WITNESS_SCALE_FACTOR returning None if an overflow occurred.
