Struct Symbol 

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

Represents a trading symbol (e.g., “AAPL”, “GOOGL”)

Examples

use nt_core::types::Symbol;

let symbol = Symbol::new("AAPL").unwrap();
assert_eq!(symbol.as_str(), "AAPL");

Implementations

impl Symbol

pub fn new(s: impl Into<String>) -> Result<Symbol, String>

Create a new Symbol, validating that it’s not empty and uppercase

Errors

Returns error if symbol is empty or contains invalid characters

pub fn as_str(&self) -> &str

Get the symbol as a string slice

Trait Implementations

impl Clone for Symbol

fn clone(&self) -> Symbol

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Symbol

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Symbol

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Symbol

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

Formats the value using the given formatter.

impl Hash for Symbol

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)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Symbol

fn eq(&self, other: &Symbol) -> 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 Symbol

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
