Struct GetOrUse

pub struct GetOrUse<N: Network> { /* private fields */ }

A get command that uses the provided default in case of failure, e.g. get.or_use accounts[r0] r1 into r2;. Gets the value stored at operand in mapping and stores the result in destination. If the key is not present, default is stored in destination.

Implementations

impl<N: Network> GetOrUse<N>

pub const fn opcode() -> Opcode

Returns the opcode.

pub fn operands(&self) -> Vec<Operand<N>>

Returns the operands in the operation.

pub const fn mapping(&self) -> &CallOperator<N>

Returns the mapping.

pub const fn key(&self) -> &Operand<N>

Returns the operand containing the key.

pub const fn default(&self) -> &Operand<N>

Returns the default value.

pub const fn destination(&self) -> &Register<N>

Returns the destination register.

impl<N: Network> GetOrUse<N>

pub fn finalize( &self, stack: &(impl StackMatches<N> + StackProgram<N>), store: &impl FinalizeStoreTrait<N>, registers: &mut (impl RegistersLoad<N> + RegistersStore<N>), ) -> Result<()>

Finalizes the command.

Trait Implementations

impl<N: Clone + Network> Clone for GetOrUse<N>

fn clone(&self) -> GetOrUse<N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N: Network> Debug for GetOrUse<N>

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

Prints the command as a string.

impl<N: Network> Display for GetOrUse<N>

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

Prints the command to a string.

impl<N: Network> FromBytes for GetOrUse<N>

fn read_le<R: Read>(reader: R) -> IoResult<Self>

Reads the command from a buffer.

fn from_bytes_le(bytes: &[u8]) -> Result<Self, Error>

where Self: Sized,

Returns Self from a byte array in little-endian order.

impl<N: Network> FromStr for GetOrUse<N>

fn from_str(string: &str) -> Result<Self>

Parses a string into the command.

type Err = Error

The associated error which can be returned from parsing.

impl<N: Network> Hash for GetOrUse<N>

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<N: Network> Parser for GetOrUse<N>

fn parse(string: &str) -> ParserResult<'_, Self>

Parses a string into an operation.

impl<N: Network> PartialEq for GetOrUse<N>

fn eq(&self, other: &Self) -> 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<N: Network> ToBytes for GetOrUse<N>

fn write_le<W: Write>(&self, writer: W) -> IoResult<()>

Writes the operation to a buffer.

fn to_bytes_le(&self) -> Result<Vec<u8>, Error>

where Self: Sized,

Returns self as a byte array in little-endian order.
