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§
source§impl Weight
impl Weight
sourcepub const ZERO: Weight = _
pub const ZERO: Weight = _
0 wu.
Equivalent to MIN
, may better express intent in some contexts.
sourcepub const MIN: Weight = _
pub const MIN: Weight = _
Minimum possible value (0 wu).
Equivalent to ZERO
, may better express intent in some contexts.
sourcepub const fn from_vb_unchecked(vb: u64) -> Self
pub const fn from_vb_unchecked(vb: u64) -> Self
Constructs Weight
from virtual bytes without overflow check.
sourcepub const fn from_witness_data_size(witness_size: u64) -> Self
pub const fn from_witness_data_size(witness_size: u64) -> Self
Constructs Weight
from witness size.
sourcepub const fn from_non_witness_data_size(non_witness_size: u64) -> Self
pub const fn from_non_witness_data_size(non_witness_size: u64) -> Self
Constructs Weight
from non-witness size.
sourcepub const fn to_wu(self) -> u64
pub const fn to_wu(self) -> u64
Returns raw weight units.
Can be used instead of into()
to avoid inference issues.
sourcepub const fn to_vbytes_floor(self) -> u64
pub const fn to_vbytes_floor(self) -> u64
Converts to vB rounding down.
sourcepub const fn to_vbytes_ceil(self) -> u64
pub const fn to_vbytes_ceil(self) -> u64
Converts to vB rounding up.
sourcepub fn checked_add(self, rhs: Self) -> Option<Self>
pub fn checked_add(self, rhs: Self) -> Option<Self>
Checked addition.
Computes self + rhs
returning None
if overflow occurred.
sourcepub fn checked_sub(self, rhs: Self) -> Option<Self>
pub fn checked_sub(self, rhs: Self) -> Option<Self>
Checked subtraction.
Computes self - rhs
returning None
if overflow occurred.
sourcepub fn checked_mul(self, rhs: u64) -> Option<Self>
pub fn checked_mul(self, rhs: u64) -> Option<Self>
Checked multiplication.
Computes self * rhs
returning None
if overflow occurred.
sourcepub fn checked_div(self, rhs: u64) -> Option<Self>
pub fn checked_div(self, rhs: u64) -> Option<Self>
Checked division.
Computes self / rhs
returning None
if rhs == 0
.
