Struct StrategyId 

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

Represents a valid strategy ID.

Implementations

impl StrategyId

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

Creates a new StrategyId instance.

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

Example: “EMACross-001”.

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

Errors

Returns an error if:

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

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

Creates a new StrategyId instance.

Panics

Panics if value is not a valid string.

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 external() -> Self

pub fn is_external(&self) -> bool

pub fn get_tag(&self) -> &str

Returns the numerical tag portion of the strategy ID.

For external strategy IDs (no separator), returns the full ID string.

type BaseType = PyAny

Base class

type ThreadChecker = NoopThreadChecker
