Struct TypesSection

pub struct TypesSection {
    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 TypesSection

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

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

pub fn is_non_returning(&self) -> bool

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>)

Encode the section into the buffer.

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

Decode the section from the input.

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

Validate the section.

Trait Implementations

impl Clone for TypesSection

fn clone(&self) -> TypesSection

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TypesSection

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

Formats the value using the given formatter.

impl Default for TypesSection

fn default() -> TypesSection

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TypesSection

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for TypesSection

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 PartialEq for TypesSection

fn eq(&self, other: &TypesSection) -> 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 Serialize for TypesSection

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 TypesSection

impl Eq for TypesSection

impl StructuralPartialEq for TypesSection

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.
