Create Mirai-based Controller (WebAssembly Compatible)

Creates a mirai-based async controller for WebAssembly environments where crew is not available. Provides crew-compatible interface.

Usage

create_mirai_controller(n_workers = 2, seconds_idle = 60)

Arguments

n_workers

Integer. Number of mirai daemons to create (default: 2).

seconds_idle

Numeric. Ignored (no mirai equivalent). Kept for interface compatibility with crew.

Value

List with crew-compatible interface:

• push(name, command, data, globals, packages): Submit task

• pop(scale): Retrieve completed task

• terminate(): Shutdown daemons

Details

This function provides a crew-compatible interface using mirai instead of crew. It's automatically used when running in WebR/WebAssembly (detected by is_webr()).

The mirai backend uses:

• mirai::daemons() for worker management

• mirai::mirai() for task submission

• Blocking mirai[] for task retrieval

Examples

if (FALSE) { # \dontrun{
# Create mirai controller
controller <- create_mirai_controller(n_workers = 2)

# Submit task (crew-compatible interface)
controller$push(
  name = "task1",
  command = sum(x),
  data = list(),
  globals = list(x = 1:10),
  packages = character()
)

# Retrieve result
result <- controller$pop()

# Clean up
controller$terminate()
} # }
