Amount

Struct Amount 

Source
pub struct Amount(/* private fields */);
Expand description

An amount of Bitcoin

Sadly, because lightning uses “milli-satoshis” we cannot directly use rust-bitcoin’s Amount type.

In general, when displaying amounts to the user, you should use Self::sats_rounding_up.

Implementations§

Source§

impl Amount

Source

pub const MAX: Amount

The maximum possible Amount, equal to 21 million BTC

Source

pub const ZERO: Amount

Zero milli-satoshis

Source

pub const fn milli_sats(&self) -> u64

The amount in milli-satoshis

Source

pub const fn sats(&self) -> Result<u64, ()>

The amount in satoshis, if it is exactly a whole number of sats.

Source

pub const fn sats_rounding_up(&self) -> u64

The amount in satoshis, rounding up to the next whole satoshi.

Source

pub const fn from_milli_sats(msats: u64) -> Result<Self, ()>

Constructs a new Amount for the given number of milli-satoshis.

Fails only if msats is greater than 21 million Bitcoin (in milli-satoshis).

Source

pub const fn from_sats(sats: u64) -> Result<Self, ()>

Constructs a new Amount for the given number of satoshis.

Fails only if sats is greater than 21 million Bitcoin (in satoshis).

Source

pub const fn saturating_add(self, rhs: Amount) -> Amount

Adds an Amount to this Amount, saturating to avoid overflowing 21 million bitcoin.

Source

pub const fn saturating_sub(self, rhs: Amount) -> Amount

Subtracts an Amount from this Amount, saturating to avoid underflowing.

Source

pub fn btc_decimal_rounding_up_to_sats(self) -> FormattedAmount

Returns an object that implements core::fmt::Display which writes out the amount, in bitcoin, with a decimal point between the whole-bitcoin and partial-bitcoin amounts, with any milli-satoshis rounded up to the next whole satoshi.
