Enum mmtk::util::options::GCTriggerSelector

pub enum GCTriggerSelector {
    FixedHeapSize(usize),
    DynamicHeapSize(usize, usize),
    Delegated,
}

Select a GC trigger for MMTk.

Variants

FixedHeapSize(usize)

GC is triggered when a fix-sized heap is full. The value specifies the fixed heap size in bytes.

DynamicHeapSize(usize, usize)

GC is triggered by internal herusticis, and the heap size is varying between the two given values. The two values are the lower and the upper bound of the heap size.

Delegated

Delegate the GC triggering to the binding. This is not supported at the moment.

Implementations

impl GCTriggerSelector

const K: u64 = 1_024u64

const M: u64 = 1_048_576u64

const G: u64 = 1_073_741_824u64

const T: u64 = 1_099_511_627_776u64

pub fn max_heap_size(&self) -> usize

get max heap size

fn parse_size(s: &str) -> Result<usize, String>

Parse a size representation, which could be a number to represents bytes, or a number with the suffix K/k/M/m/G/g. Return the byte number if it can be parsed properly, otherwise return an error string.

fn validate(&self) -> bool

Return true if the gc trigger is valid

Trait Implementations

impl Clone for GCTriggerSelector

fn clone(&self) -> GCTriggerSelector

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GCTriggerSelector

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for GCTriggerSelector

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for GCTriggerSelector

fn eq(&self, other: &GCTriggerSelector) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
