Trait Implementations

impl Clone for NearGas

fn clone(&self) -> NearGas

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NearGas

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

Formats the value using the given formatter.

impl Default for NearGas

fn default() -> NearGas

Returns the “default value” for a type.

impl Display for NearGas

NearGas Display implementation rounds up the gas usage to the relevant precision point. There are 4 breakpoints:

1. exactly 0 Tgas
2. <0.001 Tgas
3. 0.001 - 0.999 Tgas (uses 3 digits after the floating point)

4. 1 Tgas (uses 1 digit after the floating point)

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

Formats the value using the given formatter.

impl FromStr for NearGas

type Err = NearGasError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for NearGas

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for NearGas

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
