Struct Identifier 

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

A validated JavaScript identifier.

Identifiers are validated at construction time to ensure they:

• Are not reserved words
• Contain only valid characters
• Don’t start with a digit

Implementations

impl Identifier

pub const RESERVED_WORDS: &'static [&'static str]

JavaScript reserved words that cannot be used as identifiers.

pub fn new(name: impl Into<String>) -> Result<Self>

Create a new identifier, validating it.

Errors

Returns an error if the identifier is:

• Empty
• A reserved word
• Contains invalid characters
• Starts with a digit

pub fn new_unchecked(name: &'static str) -> Self

Create an identifier without validation (for trusted input).

Safety

This is not unsafe in the memory sense, but it bypasses validation. Only use for identifiers known to be valid at compile time.

pub fn as_str(&self) -> &str

Get the identifier string.

Trait Implementations

impl Clone for Identifier

fn clone(&self) -> Identifier

Returns a duplicate 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

Formats the value using the given formatter.

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

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Identifier

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

Formats the value using the given formatter.

impl Hash for Identifier

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 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

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

impl Serialize for Identifier

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
