Enum StackValue

pub enum StackValue {
    Uint(u64),
    Bytes(Vec<u8>),
}

Stack value type that can hold different types of data

Variants

Uint(u64)

Unsigned 64-bit integer

Bytes(Vec<u8>)

Byte array (used for addresses, hashes, strings, etc.)

Implementations

impl StackValue

pub fn uint(value: u64) -> Self

Create a new uint value

pub fn bytes(value: Vec<u8>) -> Self

Create a new bytes value

pub fn from_string(s: &str) -> Self

Create a new bytes value from a string

pub fn as_uint(&self) -> Result<u64, AvmError>

Get the uint value, returning an error if not a uint

pub fn as_bytes(&self) -> Result<&[u8], AvmError>

Get the bytes value, returning an error if not bytes

pub fn as_bytes_mut(&mut self) -> Result<&mut Vec<u8>, AvmError>

Get the bytes value as a mutable reference

pub fn as_bool(&self) -> Result<bool, AvmError>

Convert to bool (0 is false, non-zero is true)

pub fn type_name(&self) -> &'static str

Get the type name as a string

pub fn is_uint(&self) -> bool

Check if this is a uint value

pub fn is_bytes(&self) -> bool

Check if this is a bytes value

pub fn uint_or_zero(&self) -> u64

Convert to uint if possible, otherwise return 0

Trait Implementations

impl Clone for StackValue

fn clone(&self) -> StackValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StackValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StackValue

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for StackValue

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

Formats the value using the given formatter.

impl From<&[u8]> for StackValue

fn from(value: &[u8]) -> Self

Converts to this type from the input type.

impl From<&str> for StackValue

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for StackValue

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for StackValue

fn from(value: Vec<u8>) -> Self

Converts to this type from the input type.

impl From<u64> for StackValue

fn from(value: u64) -> Self

Converts to this type from the input type.

impl PartialEq for StackValue

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
