Struct StackReq 

pub struct StackReq {
    pub size: usize,
    pub align: usize,
}

Represents the memory requirements for an operation.

This is used to pre-compute the scratch space needed for algorithms, allowing efficient allocation strategies.

Fields

size: usize

Size in bytes.

align: usize

Alignment in bytes.

Implementations

impl StackReq

pub const ZERO: StackReq

Zero requirements.

pub const fn new(size: usize, align: usize) -> Self

Creates a new stack requirement.

pub const fn new_for<T>(count: usize) -> Self

Creates a requirement for a given type and count.

pub const fn and(self, other: Self) -> Self

Combines two requirements (both must be satisfied).

pub const fn or(self, other: Self) -> Self

Takes the maximum of two requirements (either one is sufficient).

pub const fn with_align(self, align: usize) -> Self

Returns the requirement aligned to a larger alignment.

Trait Implementations

impl Clone for StackReq

fn clone(&self) -> StackReq

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StackReq

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

Formats the value using the given formatter.

impl PartialEq for StackReq

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

Tests for self and other values to be equal, and is used by ==.

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

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