Struct FirecrackerExecutorBuilder

pub struct FirecrackerExecutorBuilder { /* private fields */ }

Implementations

impl FirecrackerExecutorBuilder

pub fn new() -> FirecrackerExecutorBuilder

pub fn determine_binary_location() -> Result<PathBuf, BuilderError>

Tries to determine firecracker binary location, in case it cannot determine any binary it will panic

It is based on multiple sources (top to bottom priority).

• FIRECRACKER_LOCATION environment variable: direct path to the binary
• $PATH environment variable: search for the binary in the directories
• firecracker binary in the current working directory

pub fn auto() -> Result<FirecrackerExecutorBuilder, BuilderError>

Create a new firecracker executor, it will try to determine the binary location, but you can provide a custom one through several options (upper take priority over lower):

• FIRECRACKER_LOCATION environment variable: direct path to the binary
• $PATH environment variable: search for the binary in the directories
• firecracker binary in the current working directory

If you provided a custom path to the binary and the binary doesn’t exist it will return BuilderError::BinaryNotFound.

If you don’t provide a directory to store firecracker related files, it will use the default one (“/srv”).
