Implementations

impl ColumnNumber

pub const fn new(number: u32) -> Option<Self>

pub const fn to_index(self) -> ColumnIndex

Convert to a ColumnIndex

pub const fn to_usize(self) -> usize

Get the raw value as a usize

pub const fn to_u32(self) -> u32

pub fn checked_add(self, offset: u32) -> Option<Self>

Add offset to this index, returning None on overflow

pub fn checked_add_signed(self, offset: i32) -> Option<Self>

Add a signed offset to this index, returning None on overflow

pub fn checked_sub(self, offset: u32) -> Option<Self>

impl<'de> Deserialize<'de> for ColumnNumber

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ColumnNumber

Converts to this type from the input type.

impl From<ColumnNumber> for ColumnIndex

fn from(index: ColumnNumber) -> Self

Converts to this type from the input type.

impl From<NonZero<u32>> for ColumnNumber

fn from(index: NonZeroU32) -> Self

impl Hash for ColumnNumber

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ColumnNumber

fn cmp(&self, other: &ColumnNumber) -> 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.
