Struct GasChange

pub struct GasChange {
    pub old_value: u64,
    pub new_value: u64,
    pub reason: i32,
    pub ordinal: u64,
}

The gas change model represents the reason why some gas cost has occurred. The gas is computed per actual op codes. Doing them completely might prove overwhelming in most cases.

Hence, we only index some of them, those that are costy like all the calls one, log events, return data, etc.

Fields

old_value: u64

new_value: u64

reason: i32

ordinal: u64

The block’s global ordinal when the gas change was recorded, refer to [Block] documentation for further information about ordinals and total ordering.

Implementations

impl GasChange

pub fn reason(&self) -> Reason

Returns the enum value of reason, or the default if the field is set to an invalid enum value.

pub fn set_reason(&mut self, value: Reason)

Sets reason to the provided enum value.

Trait Implementations

impl Clone for GasChange

fn clone(&self) -> GasChange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GasChange

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

Formats the value using the given formatter.

impl Default for GasChange

fn default() -> GasChange

Returns the “default value” for a type.

impl Message for GasChange

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for GasChange

fn eq(&self, other: &GasChange) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
