Struct ProcessMemoryLimit 

pub struct ProcessMemoryLimit { /* private fields */ }

Represents process memory limit.

Implementations

impl ProcessMemoryLimit

pub fn detect() -> RuntimeResult<Self>

Detects the effective process memory limit.

Errors

Returns an operational error when process, cgroup, or environment discovery cannot provide a finite limit.

pub fn detect_with_view(view: &dyn MemoryFileView) -> RuntimeResult<Self>

Detects the effective process memory limit through an injectable file view.

The explicit environment override wins. Otherwise the cgroup membership and mounts are read from the view when the platform uses them, and the smallest finite hard limit wins over the host physical memory fallback. A HostPhysicalMemory source on Linux means no finite cgroup hard limit was visible from this process’s membership, so the kernel may enforce a tighter constraint than the reported one.

Errors

Returns a configuration error when the explicit environment value is not a positive byte count, and an operational error when the view cannot read a file that exists or when no finite constraint is discoverable.

pub fn configured(bytes: u64) -> Result<Self, RuntimeContractViolation>

Creates an explicitly configured process memory limit.

Errors

Returns a contract violation when bytes is zero.

pub const fn bytes(self) -> u64

Returns the bytes.

pub const fn source(self) -> MemoryLimitSource

Returns the source.

pub fn fraction( self, numerator: u64, denominator: u64, ) -> Result<u64, RuntimeContractViolation>

Returns a positive bounded fraction of this limit.

Errors

Returns a contract violation for a zero, inverted, or out-of-range fraction.
