Enum MemoryBudget 

pub enum MemoryBudget {
    Auto,
    Bytes(u64),
    PercentTotal(f64),
    PercentAvailable(f64),
}

A requested memory limit.

Variants

Auto

Automatically use 80% of currently available memory.

Bytes(u64)

An absolute number of bytes.

PercentTotal(f64)

A fraction in (0, 1] of total physical capacity.

PercentAvailable(f64)

A fraction in (0, 1] of currently available capacity.

Implementations

impl MemoryBudget

pub const fn bytes(bytes: u64) -> Self

Creates an absolute byte budget.

pub fn percent_total(percent: f64) -> MemoryResult<Self>

Creates a percentage-of-total budget.

Errors

Returns MemoryError::InvalidBudget unless percent is in (0, 100].

pub fn percent_available(percent: f64) -> MemoryResult<Self>

Creates a percentage-of-available budget.

Errors

Returns MemoryError::InvalidBudget unless percent is in (0, 100].

pub fn resolve(self, resource: &MemoryResource) -> MemoryResult<u64>

Resolves this request for a resource snapshot.

Errors

Returns an error for zero budgets, invalid percentages, or unavailable capacity telemetry.
