Struct Constraint 

pub struct Constraint {
    pub size: u64,
    pub min: u64,
    pub max: u64,
    pub align: u64,
    pub policy: AllocPolicy,
}

Struct to declare resource allocation constraints.

Fields

size: u64

Size of resource to allocate.

min: u64

Lower boundary for resource allocation.

max: u64

Upper boundary for resource allocation.

align: u64

Alignment for allocated resource.

policy: AllocPolicy

Policy for resource allocation.

Implementations

impl Constraint

pub fn new<T>(size: T) -> Self

where u64: From<T>,

pub fn min<T>(self, min: T) -> Self

where u64: From<T>,

pub fn max<T>(self, max: T) -> Self

where u64: From<T>,

Set the upper boundary constraint for resource allocation.

pub fn align<T>(self, align: T) -> Self

where u64: From<T>,

Set the alignment constraint for allocated resource.

pub fn policy(self, policy: AllocPolicy) -> Self

Set the resource allocation policy.

pub fn validate(&self) -> Result<()>

Validate the resource allocation constraints.
