Struct TraderId 

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

Represents a valid trader ID.

Implementations

impl TraderId

pub fn new_checked<T: AsRef<str>>(value: T) -> CorrectnessResult<Self>

Creates a new TraderId instance.

Must be correctly formatted with two valid strings either side of a hyphen. It is expected a trader ID is the abbreviated name of the trader with an order ID tag number separated by a hyphen.

Example: “TESTER-001”.

The reason for the numerical component of the ID is so that order and position IDs do not collide with those from another node instance.

Errors

Returns an error if:

• value is not a valid ASCII string.
• value does not contain a hyphen ‘-’ separator.
• Either the name or tag part (before/after the hyphen) is empty.

Notes

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

pub fn new<T: AsRef<str>>(value: T) -> Self

Creates a new TraderId instance.

Panics

Panics if value is not a valid string, or does not contain a hyphen ‘-’ separator.

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 get_tag(&self) -> &str

Returns the numerical tag portion of the trader ID.

Panics

Panics if the internal ID string does not contain a ‘-’ separator.

pub fn external() -> Self

Creates an external trader ID used for orders from external sources.

pub fn is_external(&self) -> bool

Returns whether this trader ID is external.
