Struct PartitionCount 

pub struct PartitionCount(/* private fields */);

A finite durable partition count for one M4 partitioned step.

Implementations

impl PartitionCount

pub fn new(value: u16) -> Result<PartitionCount, PlanError>

Constructs a count in the accepted 1..=1024 range.

Errors

Returns PlanError::InvalidPartitionCount outside that range.

pub const fn get(self) -> u16

Returns the declared partition count.

Trait Implementations

impl Eq for PartitionCount

impl Hash for PartitionCount

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for PartitionCount

fn cmp(&self, other: &PartitionCount) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PartitionCount

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for PartitionCount

fn partial_cmp(&self, other: &PartitionCount) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
