Struct Symbol

#[repr(C)]
pub struct Symbol(/* private fields */);

Represents a valid ticker symbol ID for a tradable instrument.

Implementations

impl Symbol

pub fn new_checked(value: &str) -> Result<Self>

Creates a new Symbol instance with correctness checking.

Error

Returns an error if value is not a valid string.

Notes

PyO3 requires a Result type for proper error handling and stacktrace printing in Python.

pub fn new(value: &str) -> Self

Creates a new Symbol instance.

Panic

• If value is not a valid string.

pub fn from_str_unchecked(s: &str) -> Self

pub fn inner(&self) -> Ustr

Returns the inner identifier value.

pub fn as_str(&self) -> &str

Returns the inner identifier value as a string slice.

pub fn is_composite(&self) -> bool

Returns true if the symbol string contains a period (.).

pub fn root(&self) -> &str

Returns the symbol root.

The symbol root is the substring that appears before the first period (.) in the full symbol string. It typically represents the underlying asset for futures and options contracts. If no period is found, the entire symbol string is considered the root.

pub fn topic(&self) -> String

Returns the symbol topic.

The symbol topic is the root symbol with a wildcard (*) appended if the symbol has a root, otherwise returns the full symbol string.
