Struct ChunkCount 

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

A checked non-negative item or transaction count.

Implementations

impl ChunkCount

pub const ZERO: Self

The zero count.

pub const fn new(value: u64) -> Self

Constructs a count.

pub const fn get(self) -> u64

Returns the numeric count.

pub fn checked_add(self, other: Self) -> Result<Self, ChunkError>

Adds two counts without wrapping.

Errors

Returns ChunkError::CountOverflow when the sum exceeds u64.

pub fn checked_increment(self) -> Result<Self, ChunkError>

Increments this count without wrapping.

Errors

Returns ChunkError::CountOverflow at u64::MAX.
