impl MMTKBuilder

pub fn new() -> Self

pub fn new_no_env_vars() -> Self

Create an MMTK builder with build-in default options, but without reading options from environment variables.

pub fn set_option(&mut self, name: &str, val: &str) -> bool

Set an option.

pub fn set_options_bulk_by_str(&mut self, options: &str) -> bool

Set multiple options by a string. The string should be key-value pairs separated by white spaces, such as threads=1 stress_factor=4096.

pub fn set_vm_layout(&mut self, constants: VMLayout)

Custom VM layout constants. VM bindings may use this function for compressed or 39-bit heap support. This function must be called before MMTk::new()

pub fn build<VM: VMBinding>(&self) -> MMTK<VM>

Build an MMTk instance from the builder.
