Implementations

impl ColumnIndex

pub const fn number(self) -> ColumnNumber

Convert to a ColumnNumber

pub const fn to_usize(self) -> usize

Get the raw index 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>

Subtract offset from this index, returning None on underflow

pub const fn saturating_add(self, offset: u32) -> Self

Add offset to this index, saturating to u32::MAX on overflow

pub const fn saturating_add_signed(self, offset: i32) -> Self

Add a signed offset to this index, saturating to 0 on underflow, and u32::MAX on overflow.

pub const fn saturating_sub(self, offset: u32) -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ColumnIndex

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ColumnIndex

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

Formats the value using the given formatter.

impl From<ColumnIndex> for ColumnNumber

fn from(index: ColumnIndex) -> Self

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<u32> for ColumnIndex

fn from(index: u32) -> Self

Converts to this type from the input type.

impl Hash for ColumnIndex

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 ColumnIndex

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

impl PartialEq for ColumnIndex

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

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

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