Function hdk::api::version

pub fn version() -> ZomeApiResult<String>

Returns the current version of the HDK as "semver" value (eg. "1.2.3-alpha4"), or version_hash, a 32-byte MD5 of the holochain-rust source, dependencies and build environment, such as "w7vyf4x77b1539rxakcqni8zdidpg7gy". If the build environment is not Nix (and thus no out or HDK_HASH environment variable is not supplied during build), a hash consisting of all "0" is returned.
