Struct solana_libra_vm::vm_string::VMString

pub struct VMString(_);

An owned string in a Move transaction.

For more details, see the module level documentation.

Methods

impl VMString

pub fn new(s: impl Into<Box<str>>) -> Self

Creates a new VMString instance.

pub fn from_utf8(vec: Vec<u8>) -> Result<Self, FromUtf8Error>

Converts a vector of bytes to a VMString.

pub fn as_vm_str(&self) -> &VMStr

Creates a borrowed version of self.

pub fn into_string(self) -> String

Converts this VMString into a String.

This is not implemented as a From trait to discourage automatic conversions -- these conversions should not typically happen.

pub fn into_bytes(self) -> Vec<u8>

Converts this VMString into a UTF-8-encoded byte sequence.

Methods from Deref<Target = VMStr>

pub fn len(&self) -> usize

Returns the length of self in bytes.

pub fn is_empty(&self) -> bool

Returns true if self has a length of zero bytes.

pub fn as_str(&self) -> &str

Converts self to a &str.

This is not implemented as a From trait to discourage automatic conversions -- these conversions should not typically happen.

pub fn as_bytes(&self) -> &[u8]

Converts self to a byte slice.

Trait Implementations

impl AsRef<VMStr> for VMString

fn as_ref(&self) -> &VMStr

Performs the conversion.

impl CanonicalDeserialize for VMString

fn deserialize(deserializer: &mut impl CanonicalDeserializer) -> Result<Self>

impl CanonicalSerialize for VMString

impl Deref for VMString

type Target = VMStr

The resulting type after dereferencing.

fn deref(&self) -> &VMStr
