Struct CodeInfo

pub struct CodeInfo {
    pub inputs: u8,
    pub outputs: u8,
    pub max_stack_size: u16,
}

Types section that contains stack information for matching code section

Fields

inputs: u8

inputs - 1 byte - 0x00-0x7F

Number of stack elements the code section consumes

outputs: u8

outputs - 1 byte - 0x00-0x80

Number of stack elements the code section returns or 0x80 for non-returning functions

max_stack_size: u16

max_stack_height - 2 bytes - 0x0000-0x03FF

Maximum number of elements ever placed onto the stack by the code section

Implementations

impl CodeInfo

pub fn new(inputs: u8, outputs: u8, max_stack_size: u16) -> CodeInfo

Returns new CodeInfo with the given inputs, outputs, and max_stack_size.

pub fn is_non_returning(&self) -> bool

Returns true if section is non-returning.

pub const fn io_diff(&self) -> i32

Calculates the difference between the number of input and output stack elements.

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

Encodes the section into the buffer.

pub fn decode(input: &[u8]) -> Result<(CodeInfo, &[u8]), EofDecodeError>

Decodes the section from the input.

pub fn validate(&self) -> Result<(), EofDecodeError>

Validates the section.

Trait Implementations

impl Clone for CodeInfo

fn clone(&self) -> CodeInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CodeInfo

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

Formats the value using the given formatter.

impl Default for CodeInfo

fn default() -> CodeInfo

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CodeInfo

fn deserialize<__D>( __deserializer: __D, ) -> Result<CodeInfo, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for CodeInfo

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

where __H: Hasher,

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 CodeInfo

fn cmp(&self, other: &CodeInfo) -> 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 CodeInfo

fn eq(&self, other: &CodeInfo) -> 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 CodeInfo

fn partial_cmp(&self, other: &CodeInfo) -> 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 CodeInfo

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for CodeInfo

impl Eq for CodeInfo

impl StructuralPartialEq for CodeInfo

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
