}Expand description
Provides a common interface for handling amounts of a cryptocurrency. Has functions to convert to and from the main unit and the smallest unit of the coin.
Required Methods§
sourcefn from_main_unit_decimal_value(value: f64) -> Self
fn from_main_unit_decimal_value(value: f64) -> Self
In the units of main “big” unit (a floating point number, not an integer subdivision) using decimal value, for bitcoin BTC, ethereum ETH, etc. The CryptoAmount is a wrapper around a floating point number and the default integer value stored is in the smallest unit of the coin. For example this would be satoshi for bitcoin, wei for ethereum, etc. The decimal value is the floating point number representation in the main unit of the coin, for example BTC, ETH, etc.
sourcefn from_smallest_unit_integer_value(value: u64) -> Self
fn from_smallest_unit_integer_value(value: u64) -> Self
Creates a new CryptoAmount from the smallest unit of the coin, for example satoshi for bitcoin, wei for ethereum, etc.
sourcefn to_main_unit_decimal_value(&self) -> f64
fn to_main_unit_decimal_value(&self) -> f64
Returns the decimal value of the CryptoAmount, this is the floating point number representation in the main unit of the coin, for example BTC, ETH, etc.
sourcefn to_smallest_unit_integer_value(&self) -> u64
fn to_smallest_unit_integer_value(&self) -> u64
Returns the integer value of the CryptoAmount, this is the integer representation in the smallest unit of the coin, for example satoshi for bitcoin, wei for ethereum, etc.
