Struct solana_libra_vm::vm_string::VMStr

#[repr(transparent)]pub struct VMStr(_);

A borrowed string in Move code.

For more details, see the module level documentation.

Methods

impl VMStr

pub fn new<'a>(s: impl AsRef<str> + 'a) -> &'a 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 Borrow<VMStr> for VMString

fn borrow(&self) -> &VMStr

Immutably borrows from an owned value.

impl CanonicalSerialize for VMStr

LCS does not define any sort of extra annotation for VM strings -- they're serialized exactly the same way regular strings are, and are represented only within the type system for now.

fn serialize(&self, serializer: &mut impl CanonicalSerializer) -> Result<()>

impl Debug for VMStr

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

Formats the value using the given formatter.

impl Display for VMStr

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

Formats the value using the given formatter.

impl Eq for VMStr

impl<'a> From<&'a VMStr> for VMString

fn from(s: &'a VMStr) -> Self

Performs the conversion.

impl<'a> From<&'a str> for &'a VMStr

fn from(s: &'a str) -> Self

Performs the conversion.

impl Hash for VMStr

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, 

Feeds a slice of this type into the given [Hasher].

impl Ord for VMStr

fn cmp(&self, other: &VMStr) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<VMStr> for VMStr

fn eq(&self, other: &VMStr) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &VMStr) -> bool

This method tests for !=.

impl PartialOrd<VMStr> for VMStr

fn partial_cmp(&self, other: &VMStr) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &VMStr) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &VMStr) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &VMStr) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &VMStr) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StructuralEq for VMStr

impl StructuralPartialEq for VMStr

impl ToOwned for VMStr

type Owned = VMString

The resulting type after obtaining ownership.

fn to_owned(&self) -> VMString

Creates owned data from borrowed data, usually by cloning.

fn clone_into(&self, target: &mut Self::Owned)

🔬 This is a nightly-only experimental API. (toowned_clone_into)

recently added

Uses borrowed data to replace owned data, usually by cloning.
