Struct EofBody

pub struct EofBody {
    pub code_info: Vec<CodeInfo>,
    pub code_section: Vec<usize>,
    pub code: Bytes,
    pub code_offset: usize,
    pub container_section: Vec<Bytes>,
    pub data_section: Bytes,
    pub is_data_filled: bool,
}

EOF container body

Contains types, code, container and data sections.

Can be used to create a new EOF container using the into_eof method.

Fields

code_info: Vec<CodeInfo>

Code information

code_section: Vec<usize>

Index of the last byte of each code section

code: Bytes

Code byte, it is a concatenation of all code sections. Interpreter uses this bytecode to execute the opcodes.

code_offset: usize

Offset of the code section in the bytecode.

container_section: Vec<Bytes>

Container sections

data_section: Bytes

Data section

is_data_filled: bool

Indicates if the data section is filled.

Unfilled data section are used in EOFCREATE/TXCREATE to append data before deploying that contract to state.

EOF containers that are in state and can be executed are required to have filled data section.

Implementations

impl EofBody

pub fn code(&self, index: usize) -> Option<Bytes>

Returns the code section at the given index.

pub fn into_eof(self) -> Eof

Creates an EOF container from this body.

pub fn eof_code_section_start(&self, idx: usize) -> Option<usize>

Returns offset of the start of indexed code section.

First code section starts at 0.

pub fn encode(&self, buffer: &mut Vec<u8>)

Encodes this body into the given buffer.

pub fn decode(input: &Bytes, header: &EofHeader) -> Result<Self, EofDecodeError>

Decodes an EOF container body from the given buffer and header.

Trait Implementations

impl Clone for EofBody

fn clone(&self) -> EofBody

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EofBody

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

Formats the value using the given formatter.

impl Default for EofBody

fn default() -> EofBody

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EofBody

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for EofBody

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 EofBody

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for EofBody

fn eq(&self, other: &EofBody) -> 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.

impl PartialOrd for EofBody

fn partial_cmp(&self, other: &EofBody) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for EofBody

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for EofBody
