Struct diem_sdk::move_types::identifier::IdentStr

pub struct IdentStr(_);

A borrowed identifier.

For more details, see the module level documentation.

Implementations

impl IdentStr

pub fn new(s: &str) -> Result<&IdentStr, Error>

pub fn is_valid(s: impl AsRef<str>) -> bool

Returns true if this string is a valid identifier.

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<IdentStr> for Identifier

fn as_ref(&self) -> &IdentStr

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<IdentStr> for Identifier

fn borrow(&self) -> &IdentStr

Immutably borrows from an owned value.

impl Debug for IdentStr

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

Formats the value using the given formatter.

impl Display for IdentStr

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

Formats the value using the given formatter.

impl From<&IdentStr> for Identifier

fn from(ident_str: &IdentStr) -> Identifier

Converts to this type from the input type.

impl Hash for IdentStr

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

impl Ord for IdentStr

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

This method returns an Ordering between self and other.

impl PartialEq<IdentStr> for IdentStr

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<IdentStr> for IdentStr

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

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

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

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

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

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

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

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

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

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

impl RefCast for IdentStr

type From = str

fn ref_cast(_from: &<IdentStr as RefCast>::From) -> &IdentStr

fn ref_cast_mut(_from: &mut <IdentStr as RefCast>::From) -> &mut IdentStr

impl ToOwned for IdentStr

type Owned = Identifier

The resulting type after obtaining ownership.

fn to_owned(&self) -> Identifier

Creates owned data from borrowed data, usually by cloning.

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

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