Variants

VU

${__VU} -> Virtual User ID (1-indexed)

Iteration

${__ITER} -> Iteration count (0-indexed)

Timestamp

${__TIMESTAMP} -> Current timestamp in milliseconds

UUID

${__UUID} -> Random UUID

${__RANDOM} -> Random float 0-1

Counter

${__COUNTER} -> Global incrementing counter

Date

${__DATE} -> Current date in ISO format

VuIter

${__VU_ITER} -> Combined VU and iteration for unique IDs

Implementations

impl DynamicPlaceholder

pub fn from_name(name: &str) -> Option<Self>

Parse a placeholder name into a variant

pub fn to_k6_expression(&self) -> &'static str

Get the k6 JavaScript expression for this placeholder

pub fn requires_import(&self) -> Option<&'static str>

Check if this placeholder requires additional k6 imports

Note: As of k6 v1.0.0+, webcrypto is globally available and no longer requires importing from ‘k6/experimental/webcrypto’. The crypto object (including crypto.randomUUID()) is available globally.

pub fn requires_global_init(&self) -> Option<&'static str>

Check if this placeholder requires global state initialization

Trait Implementations

impl Clone for DynamicPlaceholder

fn clone(&self) -> DynamicPlaceholder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DynamicPlaceholder

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

Formats the value using the given formatter.

impl Hash for DynamicPlaceholder

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 DynamicPlaceholder

fn eq(&self, other: &DynamicPlaceholder) -> 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.
