Struct Remove 

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

A remove command, e.g. remove mapping[r0]; Removes the (key, value) entry in mapping.

Implementations

impl<N: Network> Remove<N>

pub const fn opcode() -> Opcode

Returns the opcode.

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

Returns the operands in the operation.

pub const fn mapping_name(&self) -> &Identifier<N>

Returns the mapping name.

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

Returns the operand containing the key.

impl<N: Network> Remove<N>

pub fn finalize( &self, stack: &impl StackTrait<N>, store: &impl FinalizeStoreTrait<N>, registers: &mut impl RegistersTrait<N>, ) -> Result<Option<FinalizeOperation<N>>>

Finalizes the command.

Trait Implementations

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

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

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

Prints the command as a string.

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

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

Prints the command to a string.

impl<N: Network> FromBytes for Remove<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.

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

where Self: Sized,

Same behavior as Self::from_bytes_le but avoids costly checks. This shall only be called when deserializing from a trusted source, such as local storage.

fn read_le_unchecked<R>(reader: R) -> Result<Self, Error>

where R: Read, Self: Sized,

Same behavior as Self::read_le but avoids costly checks. This shall only be called when deserializing from a trusted source, such as local storage.

fn read_le_with_unchecked<R>(reader: R, unchecked: bool) -> Result<Self, Error>

where R: Read, Self: Sized,

Helper function that deserializes either unchecked or checked based on the given boolean flag.

impl<N: Network> FromStr for Remove<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: Hash + Network> Hash for Remove<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 Remove<N>

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

Parses a string into an operation.

impl<N: PartialEq + Network> PartialEq for Remove<N>

fn eq(&self, other: &Remove<N>) -> 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 Remove<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.
