Struct Identifier

pub struct Identifier(/* private fields */);

An owned identifier.

For more details, see the module level documentation.

Implementations

impl Identifier

pub fn new(s: impl Into<Box<str>>) -> Result<Identifier, Error>

Creates a new Identifier instance.

pub unsafe fn new_unchecked(s: impl Into<Box<str>>) -> Identifier

Creates a new Identifier from a string without checking if it is a valid identifier. This should not be used under normal circumstances, but is used in cases where we need to preserve backwards compatibility.

Safety

Only use this function when preserving backwards compatibility.

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

Returns true if this string is a valid identifier.

pub fn is_self(&self) -> bool

Returns if this identifier is <SELF>. TODO: remove once we fully separate CompiledScript & CompiledModule.

pub fn from_utf8(vec: Vec<u8>) -> Result<Identifier, Error>

Converts a vector of bytes to an Identifier.

pub fn as_ident_str(&self) -> &IdentStr

Creates a borrowed version of self.

pub fn into_string(self) -> String

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

Methods from Deref<Target = IdentStr>

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.

pub fn abstract_size_for_gas_metering(&self) -> GasQuantity<AbstractMemoryUnit>

Returns the abstract size of the struct TODO (ade): use macro to enfornce determinism

Trait Implementations

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Identifier

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

Formats the value using the given formatter.

impl Deref for Identifier

Dereferences the value.

impl<'de> Deserialize<'de> for Identifier

fn deserialize<__D>( __deserializer: __D, ) -> Result<Identifier, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Identifier

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 FromStr for Identifier

type Err = Error

The associated error which can be returned from parsing.

fn from_str(data: &str) -> Result<Identifier, Error>

Parses a string s to return a value of this type.

impl Hash for Identifier

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

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

impl Ord for Identifier

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl PartialEq for Identifier

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

Tests for self and other values to be equal, and is used by ==.

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