Struct mmtk::util::options::NurserySize

pub struct NurserySize {
    pub kind: NurseryKind,
    pub min: usize,
    /* private fields */
}

An option that provides a min/max interface to MMTk and a Bounded/Fixed interface to the user/VM.

Fields

kind: NurseryKind

The nursery type

min: usize

Minimum nursery size (in bytes)

Implementations

impl NurserySize

pub fn new(kind: NurseryKind, value: Option<usize>) -> Self

Create a NurserySize with the given kind. The value argument specifies the nursery size for a fixed nursery, or specifies the max size for a bounded nursery.

pub fn parse(s: &str) -> Result<NurserySize, String>

Returns a NurserySize or String containing error. Expects nursery size to be formatted as <NurseryKind>:<size in bytes>. For example, Fixed:8192 creates a NurseryKind::Fixed nursery of size 8192 bytes.
