embeddedbinary can embed a binary inside a Go binary, and provides functions to execute it.

Embedded binaries are compressed to save on size. They require temporary disk space to execute, but the disk space is automatically freed when the child program exits.

Use the embedded_binary_go_library rule defined in defs.bzl.

load(".../defs.bzl", "embedded_binary_go_library")

# Declare a binary target:
go_binary(
    name = "my_binary",
    srcs = ["my_binary.go"],
)

# Generate a go_library rule that can execute the binary target:
embedded_binary_go_library(
    name = "my_library",
    binary = ":my_binary",
)

See test/BUILD under this directory for a full example.
